optional #GCancellable object, or %NULL
Adds a copy of zone to cache and emits an
#ETimezoneCache::timezone-added signal. The cache will use the TZID
string returned by i_cal_timezone_get_tzid() as the lookup key, which can
be passed to e_timezone_cache_get_timezone() to obtain zone again.
If the cache already has an #ICalTimezone with the same TZID string
as zone, the cache will remain unchanged to avoid invalidating any
#ICalTimezone pointers which may have already been returned through
e_timezone_cache_get_timezone().
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.

The returned string is an iCal string for that ICalTimezone and
should be freed with g_free() when no longer needed.

Erases the cache and all of its content from the disk.
The only valid operation after this is to free the cache.
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().
Calls func for each found object, which satisfies the criteria
for both deleted_flag and where_clause.
Note the func should not call any SQLite commands, because it's invoked
within a SELECT statement execution.

optional #GCancellable object, or %NULL
Calls func for each found object, which satisfies the criteria for both
deleted_flag and where_clause, letting the caller update values where
necessary. The return value of func is used to determine whether the call
was successful, not whether there are any changes to be saved. If anything
fails during the call then the all changes are reverted.
When there are requested any changes by the func, this function also
calls e_cache_copy_missing_to_column_values() to ensure no descendant
column data is lost.

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.
Freezes automatic revision change for the cache. The function
can be called multiple times, but each such call requires its
pair function e_cache_thaw_revision_change() call. See also
e_cache_change_revision().
Returns an object with the given uid. This function does not consider locally
deleted objects. The out_revision is set to the object revision, if not %NULL.
Free it with g_free() when no longer needed. Similarly the out_other_columns
contains a column name to column value strings for additional columns which had
been requested when calling e_cache_initialize_sync(), if not %NULL.
Free the returned #ECacheColumnValues with e_cache_column_values_free(), when
no longer needed.
a unique identifier of an object

The same as e_cache_get(), only considers also locally deleted objects.
a unique identifier of an object
optional #GCancellable object, or %NULL
Gets a list of objects stored in the cache, optionally together with
their revisions. The uids are not returned in any particular order,
but the position between out_objects and out_revisions matches
the same object.
Both out_objects and out_revisions contain newly allocated #GSList, which
should be freed with g_slist_free_full (slist, g_free); when no longer needed.
one of #ECacheDeletedFlag enum
optional #GCancellable object, or %NULL
The same as e_cache_get_offline_changes(), only splits the saved UID into UID and RID and saved the data into #ECalCacheOfflineChange structure.
optional #GCancellable object, or %NULL
Gathers the list of all offline changes being done so far. The returned #GSList contains #ECacheOfflineChange structure. Use e_cache_clear_offline_changes() to clear all offline changes at once.

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.

This function gets back user data pointers stored via g_object_set_qdata().
A #GQuark, naming the user data pointer
Gets a timezone with given tzid, which had been previously put
into the cal_cache with e_cal_cache_put_timezone().
The returned ICalTimezone is owned by the cal_cache and should
not be freed.
a timezone ID to get
optional #GCancellable object, or %NULL
Obtains an #ICalTimezone by its TZID string. If no match is found,
the function returns %NULL. The returned #ICalTimezone is owned by
the cache and should not be modified or freed.
the TZID of a timezone
Gets a list of unique object identifiers stored in the cache, optionally
together with their revisions. The uids are not returned in any particular
order, but the position between out_uids and out_revisions matches
the same object.
Both out_uids and out_revisions contain newly allocated #GSList, which
should be freed with g_slist_free_full (slist, g_free); when no longer needed.

Checks whether object has a [floating][floating-ref] reference.
Returns a list of #EExtension objects bound to extensible whose
types are ancestors of extension_type. For a complete list of
extension objects bound to extensible, pass %E_TYPE_EXTENSION.
The list itself should be freed with g_list_free(). The extension
objects are owned by extensible and should not be unreferenced.

Gets a list of all stored timezones by the cal_cache.
Only the returned list should be freed with g_list_free()
when no longer needed; the #ICalTimezone-s are owned
by the cal_cache.
Note: The list can contain timezones previously stored
in the cache, but removed from it since they were loaded,
because these are freed only when also the cal_cache is freed.
optional #GCancellable object, or %NULL
Returns a list of #ICalTimezone instances that were explicitly added to
the cache through e_timezone_cache_add_timezone(). In particular, any
built-in time zone data that e_timezone_cache_get_timezone() may use to
match a TZID string is excluded from the returned list.
Free the returned list with g_list_free(). The list elements are owned
by the cache and should not be modified or freed.
Creates an instance of all instantiable subtypes of #EExtension which
target the class of extensible. The lifetimes of these newly created
#EExtension objects are bound to extensible such that they are finalized
when extensible is finalized.
Locks the cache thus other threads cannot use it.
This can be called recursively within one thread.
Each call should have its pair e_cache_unlock().

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.
Stores an object into the cache. Depending on offline_flag, this update
the object's offline state accordingly. When the offline_flag is set
to %E_CACHE_IS_ONLINE, then it's set to #E_OFFLINE_STATE_SYNCED, like
to be fully synchronized with the server, regardless of its previous
offline state. Overwriting locally deleted object behaves like an addition
of a completely new 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().
Removes the object with the given uid from the cache. Based on the offline_flag,
it can remove also any information about locally made offline changes. Removing
the object with %E_CACHE_IS_OFFLINE will still remember it for later use

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.
Thaws automatic revision change for the cache. It's the pair
function of e_cache_freeze_revision_change().
Unlocks the cache which was previouly locked with e_cache_lock().
The cache locked with #E_CACHE_LOCK_WRITE should use either
action #E_CACHE_UNLOCK_COMMIT or #E_CACHE_UNLOCK_ROLLBACK,
while the #E_CACHE_LOCK_READ should use #E_CACHE_UNLOCK_NONE action.
an #ECacheUnlockAction
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.

Find the #GParamSpec with the given name for an

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.
