Methods / Constructors
Method / Constructor		Defined By
	new Gst.Object (Object *properties) Create a new Gst.Object Create a new Gst.Object Parameters: Object properties*
	Gst.Object.check_uniqueness (Array *list, String name) : Boolean Checks to see if there is any object named name* in list. Checks to see if there is any object named name in list. This function does not do any locking of any kind. You might want to protect the provided list with the lock of the owner of the list. This function will lock each GstObject in the list to compare the name, so be carefull when passing a list with a locked object. FALSE if it does. MT safe. Grabs and releases the LOCK of each object in the list. Parameters: Array list Required (not null) String name Required (not null) Returns: Boolean	Gst.Object
	Gst.Object.default_deep_notify (Object *object, Object orig, ParamSpec pspec, Array excluded_props) : none A default deep_notify signal callback for an object. A default deep_notify signal callback for an object. The user data should contain a pointer to an array of strings that should be excluded from the notify. The default handler will print the new value of the property using g_print. MT safe. This function grabs and releases object's LOCK for getting its path string. Parameters: GObject.Object object* Required (not null) Gst.Object orig Required (not null) GObject.ParamSpec pspec Required (not null) Array excluded_props Required (not null) NULL to show all changes. Returns: none	Gst.Object
	Gst.Object.ref_sink (void* *object) : none Increase the reference count of object, and possibly remove the floating reference, if object* has a floating reference. Increase the reference count of object, and possibly remove the floating 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. MT safe. This function grabs and releases object lock. Parameters: void* object Required (not null) Returns: none	Gst.Object
	Gst.Object.sink (void* *object) : none If object* was floating, the GST_OBJECT_FLOATING flag is removed and object is unreffed. If object was floating, the GST_OBJECT_FLOATING flag is removed and object is unreffed. When object was not floating, this function does nothing. Any newly created object has a refcount of 1 and is floating. This function should be used when creating a new object to symbolically 'take ownership' of object. This done by first doing a gst_object_ref() to keep a reference to object and then gst_object_sink() to remove and unref any floating references to object. Use gst_object_set_parent() to have this done for you. MT safe. This function grabs and releases object lock. Parameters: void* object Required (not null) Returns: none	Gst.Object
	default_error (Object *error, String debug) : none A default error function. A default error function. The default handler will simply print the error string using g_print. Parameters: Object error* Required (not null) String debug Required (not null) Returns: none	Gst.Object
	get_name () : String Returns a copy of the name of object. Returns a copy of the name of object. Caller should g_free() the return value after usage. For a nameless object, this returns NULL, which you can safely g_free() as well. MT safe. This function grabs and releases object's LOCK. Returns: String after usage.	Gst.Object
	get_name_prefix () : String Returns a copy of the name prefix of object. Returns a copy of the name prefix of object. Caller should g_free() the return value after usage. For a prefixless object, this returns NULL, which you can safely g_free() as well. MT safe. This function grabs and releases object's LOCK. Returns: String after usage.	Gst.Object
	get_parent () : Gst.Object Returns the parent of object. Returns the parent of object. This function increases the refcount of the parent object so you should gst_object_unref() it after usage. MT safe. Grabs and releases object's LOCK. Returns: Gst.Object parent. unref after usage.	Gst.Object
	get_path_string () : String Generates a string describing the path of object in the object hierarchy. Generates a string describing the path of object in the object hierarchy. Only useful (or used) for debugging. MT safe. Grabs and releases the GstObject's LOCK for all objects in the hierarchy. Returns: String g_free() the string after usage.	Gst.Object
	has_ancestor (Object *ancestor) : Boolean Check if object* has an ancestor ancestor somewhere up in the hierarchy. Check if object has an ancestor ancestor somewhere up in the hierarchy. MT safe. Grabs and releases object's locks. Parameters: Gst.Object ancestor Required (not null) Returns: Boolean	Gst.Object
	replace (Object *newobj) : none Unrefs the GstObject* pointed to by oldobj, refs newobj and puts newobj in *oldobj. Unrefs the GstObject pointed to by oldobj, refs newobj and puts newobj in *oldobj. Be carefull when calling this function, it does not take any locks. You might want to lock the object owning oldobj pointer before calling this function. Make sure not to LOCK oldobj because it might be unreffed which could cause a deadlock when it is disposed. Parameters: Gst.Object newobj Required (not null) Returns: none	Gst.Object
	restore_thyself (Node *self) : none Restores object* with the data from the parent XML node. Restores object with the data from the parent XML node. Parameters: libxml2.Node self Required (not null) Returns: none	Gst.Object
	save_thyself (Node *parent) : libxml2.Node Saves object* into the parent XML node. Saves object into the parent XML node. Parameters: libxml2.Node parent Required (not null) Returns: libxml2.Node	Gst.Object
	set_name (String *name) : Boolean Sets the name of object, or gives object* a guaranteed unique name (if name is NULL). Sets the name of object, or gives object a guaranteed unique name (if name is NULL). This function makes a copy of the provided name, so the caller retains ownership of the name it sent. a parent cannot be renamed, this function returns FALSE in those cases. MT safe. This function grabs and releases object's LOCK. Parameters: String name Required (not null) Returns: Boolean	Gst.Object
	set_name_prefix (String *name_prefix) : none Sets the name prefix of object* to name_prefix. Sets the name prefix of object to name_prefix. This function makes a copy of the provided name prefix, so the caller retains ownership of the name prefix it sent. MT safe. This function grabs and releases object's LOCK. Parameters: String name_prefix Required (not null) Returns: none	Gst.Object
	set_parent (Object *parent) : Boolean Sets the parent of object* to parent. Sets the parent of object to parent. The object's reference count will be incremented, and any floating reference will be removed (see gst_object_sink()). This function causes the parent-set signal to be emitted when the parent was successfully set. already had a parent or object and parent are the same. MT safe. Grabs and releases object's LOCK. Parameters: Gst.Object parent Required (not null) Returns: Boolean	Gst.Object
	unparent () : none Clear the parent of object, removing the associated reference. Clear the parent of object, removing the associated reference. This function decreases the refcount of object. MT safe. Grabs and releases object's lock. Returns: none	Gst.Object
