autoSplitThreshold: number

Transparently split queries with count requests bigger than a certain threshold into smaller queries.

gTypeInstance: TypeInstance
parent: GObject.Object
plugin: Grl.Plugin

Plugin the source belongs to

rank: number

Source rank

sourceDesc: string

A description of the source

sourceIcon: Gio.Icon

#GIcon representing the source

sourceId: string

The identifier of the source.

sourceName: string

The name of the source.

sourceTags: string[]

A string array of tags relevant this source.

The tags are arbitrary, and applications should just pass over the tags it does not understand. Applications would usually use this to either group sources together, or hide certain sources: a radio application would filter for %GRL_MEDIA_TYPE_AUDIO in GrlSource::supported-media as well as "radio" being listed in the tags.

To avoid irrelevant content being listed in applications, sources such as generic video sites should not be tagged as "cinema" or "tv" as they contain a lot of content that's not either of those.

This is a list of commonly used values:

  • "cinema", or "tv" The content served is from cinema or TV sources. For example, a source for movie trailers would select the former, a source for streaming live TV would select the latter.

  • "radio" The content served is from streaming radios.

  • "music" The content served is music, for example, music stores such as Jamendo or Magnatune.

  • "country:country-code" The content is mostly relevant to users from a particular country, such as a national broadcaster. For example, BBC content would be tagged as "country:uk". Country codes should be an ISO-639-1 or ISO-639-2 code.

  • "protocol:protocol-name" The content browsing or searching uses a particular protocol, such as DLNA/UPnP or DMAP/DAAP. This makes it easier to whitelist or blacklist sources rather than matching the implementation specific source ID. Examples are "protocol:dlna" and "protocol:dmap".

  • "localhost", or "localuser" The content is served from the machine the application is running on, or by an application the user is running. Applications might choose to avoid showing the user's own data in their interfaces, or integrate it in the user's local collection.

    "net:local", or "net:internet" The source requires a connection to the local network, or a connection to the Internet. Sources with those tags will be automatically hidden from the application's reach when such networks aren't available, or we're not connected to a network.

    "net:plaintext" The source makes requests over plain text, non-encrypted, network channels, such as using HTTP to do searches or lookups. Applications would usually disable those by default, so that privacy is respected by default, and no data is leaked unintentionally.

supportedMedia: SupportedMedia

List of supported media types by this source.

$gtype: GType<Grl.Source>
name: string

Methods

  • Creates a binding between source_property on source and target_property on target.

    Whenever the source_property is changed the target_property is updated using the same value. For instance:

      g_object_bind_property (action, "active", widget, "sensitive", 0);
    

    Will result in the "sensitive" property of the widget #GObject instance to be updated with the same value of the "active" property of the action #GObject instance.

    If flags contains %G_BINDING_BIDIRECTIONAL then the binding will be mutual: if target_property on target changes then the source_property on source will be updated as well.

    The binding will automatically be removed when either the source or the target instances are finalized. To remove the binding without affecting the source and the target you can just call g_object_unref() on the returned #GBinding instance.

    Removing the binding by calling g_object_unref() on it must only be done if the binding, source and target are only used from a single thread and it is clear that both source and target outlive the binding. Especially it is not safe to rely on this if the binding, source or target can be finalized from different threads. Keep another reference to the binding and use g_binding_unbind() instead to be on the safe side.

    A #GObject can have multiple bindings.

    Parameters

    • sourceProperty: string

      the property on source to bind

    • target: GObject.Object

      the target #GObject

    • targetProperty: string

      the property on target to bind

    • flags: BindingFlags

      flags to pass to #GBinding

    Returns Binding

  • Creates a binding between source_property on source and target_property on target, allowing you to set the transformation functions to be used by the binding.

    This function is the language bindings friendly version of g_object_bind_property_full(), using #GClosures instead of function pointers.

    Parameters

    • sourceProperty: string

      the property on source to bind

    • target: GObject.Object

      the target #GObject

    • targetProperty: string

      the property on target to bind

    • flags: BindingFlags

      flags to pass to #GBinding

    • transformTo: TClosure<any, any>

      a #GClosure wrapping the transformation function from the source to the target, or %NULL to use the default

    • transformFrom: TClosure<any, any>

      a #GClosure wrapping the transformation function from the target to the source, or %NULL to use the default

    Returns Binding

  • forceFloating(): void
  • This function is intended for #GObject implementations to re-enforce a [floating][floating-ref] object reference. Doing this is seldom required: all #GInitiallyUnowneds are created with a floating reference which usually just needs to be sunken by calling g_object_ref_sink().

    Returns void

  • freezeNotify(): void
  • Increases the freeze count on object. If the freeze count is non-zero, the emission of "notify" signals on object is stopped. The signals are queued until the freeze count is decreased to zero. Duplicate notifications are squashed so that at most one #GObject::notify signal is emitted for each property modified while the object is frozen.

    This is necessary for accessors that modify multiple properties to prevent premature notification while the object is still being modified.

    Returns void

  • getAutoSplitThreshold(): number
  • Gets how much elements the source is able to handle in a single request.

    See #grl_source_set_auto_split_threshold()

    Returns number

  • Get the capabilities of source for operation.

    Parameters

    • operation: Grl.SupportedOps

      a supported operation. Even though the type allows to specify several operations, only one should be provided here.

    Returns Grl.Caps

  • getData(key?: string): object
  • Gets a named field from the objects table of associations (see g_object_set_data()).

    Parameters

    • Optional key: string

      name of the key for that association

    Returns object

  • getDescription(): string
  • getId(): string
  • Creates an instance of #GrlMedia representing the media resource exposed at uri.

    It is recommended to call grl_source_test_media_from_uri() before invoking this to check whether the target source can theoretically do the resolution.

    This method is asynchronous.

    Parameters

    • uri: string

      A URI that can be used to identify a media resource

    • keys: number[]

      A list of keys to resolve

    • options: Grl.OperationOptions

      options wanted for that operation

    • callback: Grl.SourceResolveCb

      the user defined callback

    Returns number

  • Creates an instance of #GrlMedia representing the media resource exposed at uri.

    It is recommended to call grl_source_test_media_from_uri() before invoking this to check whether the target source can theoretically do the resolution.

    This method is synchronous.

    Parameters

    • uri: string

      A URI that can be used to identify a media resource

    • keys: number[]

      a list of keys to resolve

    • options: Grl.OperationOptions

      options wanted for that operation

    Returns Grl.Media

  • getName(): string
  • getProperty(propertyName?: string, value?: any): void
  • Gets a property of an object.

    The value can be:

    • an empty #GValue initialized by %G_VALUE_INIT, which will be automatically initialized with the expected type of the property (since GLib 2.60)
    • a #GValue initialized with the expected type of the property
    • a #GValue initialized with a type to which the expected type of the property can be transformed

    In general, a copy is made of the property contents and the caller is responsible for freeing the memory by calling g_value_unset().

    Note that g_object_get_property() is really intended for language bindings, g_object_get() is much more convenient for C programming.

    Parameters

    • Optional propertyName: string

      the name of the property to get

    • Optional value: any

      return location for the property value

    Returns void

  • getQdata(quark: number): object
  • This function gets back user data pointers stored via g_object_set_qdata().

    Parameters

    • quark: number

      A #GQuark, naming the user data pointer

    Returns object

  • getRank(): number
  • getTags(): string[]
  • getv(names: string[], values: any[]): void
  • Gets n_properties properties for an object. Obtained properties will be set to values. All properties must be valid. Warnings will be emitted and undefined behaviour may result if invalid properties are passed in.

    Parameters

    • names: string[]

      the names of each property to get

    • values: any[]

      the values of each property to get

    Returns void

  • isFloating(): boolean
  • mayResolve(media: Grl.Media, keyId: number, missingKeys: number[]): boolean
  • Checks whether key_id may be resolved with source for media, so that the caller can avoid calling grl_source_resolve() if it can be known in advance it will fail.

    If the resolution is known to be impossible because more keys are needed in media, and missing_keys is not NULL, it is populated with the list of GrlKeyID that would be needed.

    This function is synchronous and should not block.

    Parameters

    • media: Grl.Media

      a media on which we want more metadata

    • keyId: number

      the key corresponding to a metadata we might want

    • missingKeys: number[]

      an optional originally empty list

    Returns boolean

  • notify(propertyName: string): void
  • Emits a "notify" signal for the property property_name on object.

    When possible, eg. when signaling a property change from within the class that registered the property, you should use g_object_notify_by_pspec() instead.

    Note that emission of the notify signal may be blocked with g_object_freeze_notify(). In this case, the signal emissions are queued and will be emitted (in reverse order) when g_object_thaw_notify() is called.

    Parameters

    • propertyName: string

      the name of a property installed on the class of object.

    Returns void

  • Emits a "notify" signal for the property specified by pspec on object.

    This function omits the property name lookup, hence it is faster than g_object_notify().

    One way to avoid using g_object_notify() from within the class that registered the properties, and using g_object_notify_by_pspec() instead, is to store the GParamSpec used with g_object_class_install_property() inside a static array, e.g.:

      enum
    {
    PROP_0,
    PROP_FOO,
    PROP_LAST
    };

    static GParamSpec *properties[PROP_LAST];

    static void
    my_object_class_init (MyObjectClass *klass)
    {
    properties[PROP_FOO] = g_param_spec_int ("foo", "Foo", "The foo",
    0, 100,
    50,
    G_PARAM_READWRITE);
    g_object_class_install_property (gobject_class,
    PROP_FOO,
    properties[PROP_FOO]);
    }

    and then notify a change on the "foo" property with:

      g_object_notify_by_pspec (self, properties[PROP_FOO]);
    

    Parameters

    • pspec: ParamSpec

      the #GParamSpec of a property installed on the class of object.

    Returns void

  • Emits "content-changed" signal to notify subscribers that a change ocurred in source.

    See #grl_source_notify_change_list() function.

    This function is intended to be used only by plugins.

    Parameters

    • media: Grl.Media

      the media which has changed, or NULL to use the root container.

    • changeType: Grl.SourceChangeType

      the type of change

    • locationUnknown: boolean

      if change has happened in media or any descendant

    Returns void

  • Emits "content-changed" signal to notify subscribers that a change ocurred in source.

    The function will take ownership of changed medias and it should not be manipulated in any way by the caller after invoking this function. If that is needed, the caller must ref the array in advance.

    See GrlSource::content-changed signal.

    This function is intended to be used only by plugins.

    Parameters

    • changedMedias: Grl.Media[]

      the list of medias that have changed

    • changeType: Grl.SourceChangeType

      the type of change

    • locationUnknown: boolean

      if change has happpened in media or any descendant

    Returns void

  • notifyChangeStart(): boolean
  • Starts emitting ::content-changed signals when source discovers changes in the content. This instructs source to setup the machinery needed to be aware of changes in the content.

    Returns boolean

  • notifyChangeStop(): boolean
  • This will drop emission of ::content-changed signals from source. When this is done source should stop the machinery required for it to track changes in the content.

    Returns boolean

  • Execute a specialized query (specific for each provider) on a media repository.

    It is different from grl_source_search() semantically, because the query implies a carefully crafted string, rather than a simple string to search.

    This method is asynchronous.

    Parameters

    • query: string

      the query to process

    • keys: number[]

      the #GList of #GrlKeyIDs to request

    • options: Grl.OperationOptions

      options wanted for that operation

    • callback: Grl.SourceResultCb

      the user defined callback

    Returns number

  • Execute a specialized query (specific for each provider) on a media repository.

    This method is synchronous.

    Parameters

    • query: string

      the query to process

    • keys: number[]

      the #GList of #GrlKeyIDs to request

    • options: Grl.OperationOptions

      options wanted for that operation

    Returns Grl.Media[]

  • Increases the reference count of object.

    Since GLib 2.56, if GLIB_VERSION_MAX_ALLOWED is 2.56 or greater, the type of object will be propagated to the return type (using the GCC typeof() extension), so any casting the caller needs to do on the return type must be explicit.

    Returns GObject.Object

  • Increase the reference count of object, and possibly remove the [floating][floating-ref] reference, if object has a floating reference.

    In other words, if the object is floating, then this call "assumes ownership" of the floating reference, converting it to a normal reference by clearing the floating flag while leaving the reference count unchanged. If the object is not floating, then this call adds a new normal reference increasing the reference count by one.

    Since GLib 2.56, the type of object will be propagated to the return type under the same conditions as for g_object_ref().

    Returns GObject.Object

  • Remove a media from the source repository.

    This method is asynchronous.

    Parameters

    Returns void

  • Remove a media from the source repository.

    This method is synchronous.

    Parameters

    • media: Grl.Media

      a data transfer object

    Returns void

  • This method is intended to fetch the requested keys of metadata of a given media to the media source.

    This method is asynchronous.

    Parameters

    Returns number

  • This method is intended to fetch the requested keys of metadata of a given media to the media source.

    This method is synchronous.

    Parameters

    • media: Grl.Media

      a data transfer object

    • keys: number[]

      the #GList of #GrlKeyIDs to request

    • options: Grl.OperationOptions

      options to pass to this operation

    Returns Grl.Media

  • runDispose(): void
  • Releases all references to other objects. This can be used to break reference cycles.

    This function should only be called from object system implementations.

    Returns void

  • Search for the text string in a source for data identified with that string.

    If text is NULL then no text filter will be applied, and thus, no media items from source will be filtered. If source does not support NULL-text search operations it should notiy the client by setting GRL_CORE_ERROR_SEARCH_NULL_UNSUPPORTED in callback's error parameter.

    This method is asynchronous.

    Parameters

    • text: string

      the text to search

    • keys: number[]

      the #GList of #GrlKeyIDs to request

    • options: Grl.OperationOptions

      options wanted for that operation

    • callback: Grl.SourceResultCb

      the user defined callback

    Returns number

  • Search for the text string in a source for data identified with that string.

    If text is NULL then no text filter will be applied, and thus, no media items from source will be filtered. If source does not support NULL-text search operations it should notiy the client by setting GRL_CORE_ERROR_SEARCH_NULL_UNSUPPORTED in the error parameter.

    This method is synchronous.

    Parameters

    • text: string

      the text to search

    • keys: number[]

      the #GList of #GrlKeyIDs to request

    • options: Grl.OperationOptions

      options wanted for that operation

    Returns Grl.Media[]

  • setAutoSplitThreshold(threshold: number): void
  • Sets how much elements the source is able to handle in a single request.

    If user, during a search or browsing operation, asks for more elements than the threshold, the request will be automatically splitted in chunks, so up to threshold elements will be asked in each request.

    Source will act as if user were asking just a chunk, and user won't notice that the request was chunked.

    This function is intended to be used only by plugins.

    Parameters

    • threshold: number

      the threshold to set

    Returns void

  • setData(key: string, data?: object): void
  • Each object carries around a table of associations from strings to pointers. This function lets you set an association.

    If the object already had an association with that name, the old association will be destroyed.

    Internally, the key is converted to a #GQuark using g_quark_from_string(). This means a copy of key is kept permanently (even after object has been finalized) — so it is recommended to only use a small, bounded set of values for key in your program, to avoid the #GQuark storage growing unbounded.

    Parameters

    • key: string

      name of the key

    • Optional data: object

      data to associate with that key

    Returns void

  • setProperty(propertyName: string, value?: any): void
  • Sets a property on an object.

    Parameters

    • propertyName: string

      the name of the property to set

    • Optional value: any

      the value

    Returns void

  • slowKeys(): number[]
  • Similar to grl_source_supported_keys(), but these keys are marked as slow because of the amount of traffic/processing needed to fetch them.

    Returns number[]

  • stealData(key?: string): object
  • Remove a specified datum from the object's data associations, without invoking the association's destroy handler.

    Parameters

    • Optional key: string

      name of the key

    Returns object

  • stealQdata(quark: number): object
  • This function gets back user data pointers stored via g_object_set_qdata() and removes the data from object without invoking its destroy() function (if any was set). Usually, calling this function is only required to update user data pointers with a destroy notifier, for example:

    void
    object_add_to_user_list (GObject *object,
    const gchar *new_string)
    {
    // the quark, naming the object data
    GQuark quark_string_list = g_quark_from_static_string ("my-string-list");
    // retrieve the old string list
    GList *list = g_object_steal_qdata (object, quark_string_list);

    // prepend new string
    list = g_list_prepend (list, g_strdup (new_string));
    // this changed 'list', so we need to set it again
    g_object_set_qdata_full (object, quark_string_list, list, free_string_list);
    }
    static void
    free_string_list (gpointer data)
    {
    GList *node, *list = data;

    for (node = list; node; node = node->next)
    g_free (node->data);
    g_list_free (list);
    }

    Using g_object_get_qdata() in the above example, instead of g_object_steal_qdata() would have left the destroy function set, and thus the partial string list would have been freed upon g_object_set_qdata_full().

    Parameters

    • quark: number

      A #GQuark, naming the user data pointer

    Returns object

  • Store the media into the parent container

    This method is asynchronous.

    Parameters

    • parent: Grl.Media

      a parent to store the data transfer objects

    • media: Grl.Media

      a data transfer object

    • flags: Grl.WriteFlags

      flags to configure specific behaviour of the operation

    • callback: Grl.SourceStoreCb

      the user defined callback

    Returns void

  • Get the values for keys from media and store it permanently. After calling this method, future queries that return this media object shall return this new values for the selected keys.

    This function is asynchronous and uses the Glib's main loop.

    Parameters

    • media: Grl.Media

      the #GrlMedia object that we want to operate on.

    • keys: number[]

      a list of #GrlKeyID whose values we want to change.

    • flags: Grl.WriteFlags

      Flags to configure specific behaviors of the operation.

    • callback: Grl.SourceStoreCb

      the callback to execute when the operation is finished.

    Returns void

  • Update keys values from media in the source. After calling this method, future queries that return this media object shall return this new value for the selected key.

    This function is synchronous.

    Parameters

    • media: Grl.Media

      the #GrlMedia object that we want to operate on

    • keys: number[]

      a list of #GrlKeyID whose values we want to change

    • flags: Grl.WriteFlags

      Flags to configure specific behaviors of the operation.

    Returns number[]

  • Store the media into the parent container.

    This method is synchronous.

    Parameters

    • parent: Grl.Media

      a #GrlMedia container to store the data transfer objects

    • media: Grl.Media

      a #GrlMedia data transfer object

    • flags: Grl.WriteFlags

      flags to configure specific behaviour of the operation

    Returns void

  • supportedKeys(): number[]
  • Get a list of #GrlKeyID, which describe a metadata types that this source can fetch and store.

    Returns number[]

  • supportedOperations(): number
  • By default the derived objects of #GrlSource can only resolve.

    Returns number

  • testMediaFromUri(uri: string): boolean
  • Tests whether source can instantiate a #GrlMedia object representing the media resource exposed at uri.

    Parameters

    • uri: string

      A URI that can be used to identify a media resource

    Returns boolean

  • thawNotify(): void
  • Reverts the effect of a previous call to g_object_freeze_notify(). The freeze count is decreased on object and when it reaches zero, queued "notify" signals are emitted.

    Duplicate notifications for each property are squashed so that at most one #GObject::notify signal is emitted for each property, in the reverse order in which they have been queued.

    It is an error to call this function when the freeze count is zero.

    Returns void

  • unref(): void
  • Decreases the reference count of object. When its reference count drops to 0, the object is finalized (i.e. its memory is freed).

    If the pointer to the #GObject may be reused in future (for example, if it is an instance variable of another object), it is recommended to clear the pointer to %NULL rather than retain a dangling pointer to a potentially invalid #GObject instance. Use g_clear_object() for this.

    Returns void

  • watchClosure(closure: TClosure<any, any>): void
  • This function essentially limits the life time of the closure to the life time of the object. That is, when the object is finalized, the closure is invalidated by calling g_closure_invalidate() on it, in order to prevent invocations of the closure with a finalized (nonexisting) object. Also, g_object_ref() and g_object_unref() are added as marshal guards to the closure, to ensure that an extra reference count is held on object during invocation of the closure. Usually, this function will be called on closures that use this object as closure data.

    Parameters

    • closure: TClosure<any, any>

      #GClosure to watch

    Returns void

  • writableKeys(): number[]
  • Similar to grl_source_supported_keys(), but these keys are marked as writable, meaning the source allows the client to provide new values for these keys that will be stored permanently.

    Returns number[]

  • compatControl(what: number, data: object): number
  • Find the #GParamSpec with the given name for an interface. Generally, the interface vtable passed in as g_iface will be the default vtable from g_type_default_interface_ref(), or, if you know the interface has already been loaded, g_type_default_interface_peek().

    Parameters

    • gIface: TypeInterface

      any interface vtable for the interface, or the default vtable for the interface

    • propertyName: string

      name of a property to look up.

    Returns ParamSpec

  • Add a property to an interface; this is only useful for interfaces that are added to GObject-derived types. Adding a property to an interface forces all objects classes with that interface to have a compatible property. The compatible property could be a newly created #GParamSpec, but normally g_object_class_override_property() will be used so that the object class only needs to provide an implementation and inherits the property description, default value, bounds, and so forth from the interface property.

    This function is meant to be called from the interface's default vtable initialization function (the class_init member of #GTypeInfo.) It must not be called after after class_init has been called for any object types implementing this interface.

    If pspec is a floating reference, it will be consumed.

    Parameters

    • gIface: TypeInterface

      any interface vtable for the interface, or the default vtable for the interface.

    • pspec: ParamSpec

      the #GParamSpec for the new property

    Returns void

  • Lists the properties of an interface.Generally, the interface vtable passed in as g_iface will be the default vtable from g_type_default_interface_ref(), or, if you know the interface has already been loaded, g_type_default_interface_peek().

    Parameters

    • gIface: TypeInterface

      any interface vtable for the interface, or the default vtable for the interface

    Returns ParamSpec[]

  • Creates a new instance of a #GObject subtype and sets its properties.

    Construction parameters (see %G_PARAM_CONSTRUCT, %G_PARAM_CONSTRUCT_ONLY) which are not explicitly specified are set to their default values.

    Parameters

    • objectType: GType<unknown>

      the type id of the #GObject subtype to instantiate

    • parameters: GObject.Parameter[]

      an array of #GParameter

    Returns GObject.Object
