Methods / Constructors
Method / Constructor		Defined By
	new Gst.TaskPool (Object *properties) Create a new Gst.TaskPool Create a new Gst.TaskPool Parameters: Object properties*
	cleanup () : none Wait for all tasks to be stopped. Wait for all tasks to be stopped. This is mainly used internally to ensure proper cleanup of internal data structures in test suites. MT safe. Returns: none	Gst.TaskPool
	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
	join (void* id) : none Join a task and/or return it to the pool. Join a task and/or return it to the pool. id is the id obtained from gst_task_pool_push(). Parameters: void* id Required (not null) Returns: none	Gst.TaskPool
	prepare () : none Prepare the taskpool for accepting gst_task_pool_push() operations. Prepare the taskpool for accepting gst_task_pool_push() operations. MT safe. Returns: none	Gst.TaskPool
	push (Function *func, void *user_data) : void Start the execution of a new thread from pool. Start the execution of a new thread from pool. function. This pointer can be NULL, you must check error to detect errors. Parameters: Function (void* *data) : void Required (not null) void* user_data Required (not null) Returns: void*	Gst.TaskPool
	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

Events - usage syntax: this.signals.EVENTNAME.connect( Function )
Event		Defined By
	deep_notify (Object *self, Object prop_object, ParamSpec prop) : none The deep notify signal is used to be notified of property changes. The deep notify signal is used to be notified of property changes. It is typically attached to the toplevel bin to receive notifications from all the elements contained in that bin. Parameters: Gst.Object self* Gst.Object prop_object GObject.ParamSpec prop Returns: {none}	Gst.Object
	object_saved (Object *self, void *xml_node) : none Trigered whenever a new object is saved to XML. Trigered whenever a new object is saved to XML. You can connect to this signal to insert custom XML tags into the core XML. Parameters: Gst.Object self* void* xml_node Returns: {none}	Gst.Object
	parent_set (Object *self, Object parent) : none Emitted when the parent of an object is set. Emitted when the parent of an object is set. Parameters: Gst.Object self* Gst.Object parent Returns: {none}	Gst.Object
	parent_unset (Object *self, Object parent) : none Emitted when the parent of an object is unset. Emitted when the parent of an object is unset. Parameters: Gst.Object self* Gst.Object parent Returns: {none}	Gst.Object
