A non-%NULL #GStrv of URI schemes supported by this protocol. If this protocol does not support addressing contacts by URI, the list is empty.
For instance, a SIP connection manager that supports calling contacts by SIP URI (sip:alice@example.com, sips:bob@example.com) or telephone number (tel:+1-555-0123) might have { "sip", "sips", "tel", NULL }.
A non-%NULL #GStrv of vCard fields supported by this protocol. If this protocol does not support addressing contacts by a vCard field, the list is empty.
For instance, a SIP connection manager that supports calling contacts by SIP URI (vCard field SIP) or telephone number (vCard field TEL) might have { "sip", "tel", NULL }.
A non-%NULL #GStrv of interfaces which provide information as to what kind of authentication channels can possibly appear before the connection reaches the CONNECTED state, or %NULL if %TP_PROTOCOL_FEATURE_CORE has not been prepared.
A #TpAvatarRequirements representing the avatar requirements on this protocol, or %NULL if %TP_PROTOCOL_FEATURE_CORE has not been prepared or if the protocol doesn't support avatars.
The D-Bus bus name for this object. Read-only except during construction.
The classes of channel that can be requested from connections to this protocol, or %NULL if this is unknown or the %TP_PROTOCOL_FEATURE_CORE feature has not been prepared.
The name of the connection manager this protocol is on.
The D-Bus daemon for this object (this object itself, if it is a TpDBusDaemon). Read-only except during construction.
The name of the protocol in a form suitable for display to users, such as "AIM" or "Yahoo!", or a string based on #TpProtocol:protocol-name (currently constructed by putting the first character in title case, but this is not guaranteed) if no better name is available or the %TP_PROTOCOL_FEATURE_CORE feature has not been prepared.
This is effectively in the C locale (international English); user interfaces requiring a localized protocol name should look one up in their own message catalog based on either #TpProtocol:protocol-name or #TpProtocol:english-name, but should use this English version as a fallback if no translated version can be found.
The #TpSimpleClientFactory used to create this proxy, or %NULL if this proxy was not created through a factory.
The name of an icon in the system's icon theme. If none was supplied by the Protocol, or the %TP_PROTOCOL_FEATURE_CORE feature has not been prepared, a default is used; currently, this is "im-" plus #TpProtocol:protocol-name.

A list of parameter names supported by this connection manager for this protocol, or %NULL if %TP_PROTOCOL_FEATURE_PARAMETERS has not been prepared.
The machine-readable name of the protocol, taken from the Telepathy D-Bus Interface Specification, such as "jabber" or "local-xmpp".
The immutable properties of this Protocol, as provided at construction time. This is a #G_VARIANT_TYPE_VARDICT #GVariant, which must not be modified.
If the immutable properties were not provided at construction time, the %TP_PROTOCOL_FEATURE_PARAMETERS and %TP_PROTOCOL_FEATURE_CORE features will both be unavailable, and this #TpProtocol object will only be useful as a way to access lower-level D-Bus calls.
The most common vCard field used for this protocol's contact identifiers, normalized to lower case, or %NULL if there is no such field or the %TP_PROTOCOL_FEATURE_CORE feature has not been prepared.
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.

Creates a binding between source_property on source and target_property

Return whether a new account can be registered on this protocol, by setting the special "register" parameter to %TRUE.
Convert a D-Bus error name into a GError as if it was returned by a method on this proxy. This method is useful when D-Bus error names are emitted in signals, such as Connection.ConnectionError and Group.MembersChangedDetailed.

Returns a list of parameter names supported by this connection manager for this protocol.
The result is copied and must be freed by the caller with g_strfreev().
Returns a list of parameters supported by this connection manager.
The returned list must be freed by the caller, for instance with
Return the presence statuses that might be supported by connections to this protocol.
It is possible that some of these statuses will not actually be supported by a connection: for instance, an XMPP connection manager would include "hidden" in this list, even though not all XMPP servers allow users to be online-but-hidden.
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().
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.
Return the #TpProtocol:avatar-requirements property
Return the #TpProtocol:cm-name property.
Gets a named field from the objects table of associations (see g_object_set_data()).

Return the same thing as the protocol-name property, for convenient use
in C code. The returned string is valid for as long as self exists.
a parameter name
Gets a property of an object.
The value can be:
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.

Return whether this proxy is known to have a particular interface. In versions older than 0.11.11, this was a macro wrapper around tp_proxy_has_interface_by_id().
For objects that discover their interfaces at runtime, this method will indicate that interfaces are missing until they are known to be present. In subclasses that define features for use with tp_proxy_prepare_async(), successfully preparing the "core" feature for that subclass (such as %TP_CHANNEL_FEATURE_CORE or %TP_CONNECTION_FEATURE_CORE) implies that the interfaces are known.
the D-Bus interface required, as a string
Return whether this proxy is known to have a particular interface, by its quark ID. This is equivalent to using g_quark_to_string() followed by tp_proxy_has_interface(), but more efficient.

a parameter name
Return a string that could identify the account with the given parameters. In most protocols that string is a normalized 'account' parameter, but some protocols have more complex requirements; for instance, on IRC, the 'account' (nickname) is insufficient, and must be combined with a server or network name.

Checks whether object has a [floating][floating-ref] reference.
Return %TRUE if feature has been prepared successfully, or %FALSE if
feature has not been requested, has not been prepared yet, or is not
available on this object at all.
(For instance, if feature is %TP_CHANNEL_FEATURE_CHAT_STATES and self
is a #TpChannel in a protocol that doesn't actually implement chat states,
or is not a #TpChannel at all, then this method will return %FALSE.)
To prepare features, call tp_proxy_prepare_async().

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.
the name of a property installed on the class of object.
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]);
the #GParamSpec of a property installed on the class of object.
#TpProxy itself does not support any features, but subclasses like #TpChannel can support features, which can either be core functionality like %TP_CHANNEL_FEATURE_CORE, or extended functionality like %TP_CHANNEL_FEATURE_CHAT_STATES.
Proxy instances start with no features prepared. When features are requested via tp_proxy_prepare_async(), the proxy starts to do the necessary setup to use those features.
tp_proxy_prepare_async() always waits for core functionality of the proxy's class to be prepared, even if it is not specifically requested: for instance, because %TP_CHANNEL_FEATURE_CORE is core functionality of a #TpChannel,
|[ TpChannel *channel = ...;
tp_proxy_prepare_async (channel, NULL, callback, user_data);
is equivalent to
|[
TpChannel *channel = ...;
GQuark features[] = { TP_CHANNEL_FEATURE_CORE, 0 };
tp_proxy_prepare_async (channel, features, callback, user_data);
If a feature represents core functionality (like %TP_CHANNEL_FEATURE_CORE), failure to prepare it will result in tp_proxy_prepare_async() finishing unsuccessfully: if failure to prepare the feature indicates that the proxy is no longer useful, it will also emit #TpProxy::invalidated.
If a feature represents non-essential functionality (like %TP_CHANNEL_FEATURE_CHAT_STATES), or is not supported by the object at all, then failure to prepare it is not fatal: tp_proxy_prepare_async() will complete successfully, but tp_proxy_is_prepared() will still return %FALSE for the feature, and accessor methods for the feature will typically return a dummy value.
Some #TpProxy subclasses automatically start to prepare their core features when instantiated, and features will sometimes become prepared as a side-effect of other actions, but to ensure that a feature is present you must generally call tp_proxy_prepare_async() and wait for the result.
an array of desired features, ending with 0; %NULL is equivalent to an array containing only 0
if not %NULL, called exactly once, when the features have all been prepared or failed to prepare, or after the proxy is invalidated
Check for error in a call to tp_proxy_prepare_async(). An error here
generally indicates that either the asynchronous call was cancelled,
or self has emitted #TpProxy::invalidated.
the result passed to the callback of tp_proxy_prepare_async()
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().
Releases all references to other objects. This can be used to break reference cycles.
This function should only be called from object system implementations.
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.

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().
A #GQuark, naming the user data pointer
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.
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.
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.
#GClosure to watch
Ensure that the known interfaces for TpProtocol have been set up. This is done automatically when necessary, but for correct overriding of library interfaces by local extensions, you should call this function before calling tp_proxy_or_subclass_hook_on_interface_add() with first argument %TP_TYPE_PROTOCOL.
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().
any interface vtable for the interface, or the default vtable for the interface
name of a property to look up.
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.
