Methods / Constructors

Method / Constructor		Defined By
	new GstBase.DataQueue (Object properties) Create a new GstBase.DataQueue Create a new GstBase.DataQueue Parameters: Object properties
	new GstBase.DataQueue.c_new (Function checkfull, void* checkdata) : GstBase.DataQueue Create a new GstBase.DataQueue Create a new GstBase.DataQueue Parameters: Function (DataQueue queue, Number visible, Number bytes, Number time, void* checkdata) : GstBase.DataQueue Required (not null) void* checkdata Required (not null) Returns: GstBase.DataQueue
	new GstBase.DataQueue.full (Function checkfull, Function fullcallback, Function emptycallback, void* checkdata) : GstBase.DataQueue Create a new GstBase.DataQueue Create a new GstBase.DataQueue Parameters: Function (DataQueue queue, Number visible, Number bytes, Number time, void* checkdata) : GstBase.DataQueue Required (not null) Function (DataQueue queue, void* checkdata) : GstBase.DataQueue Required (not null) Function (DataQueue queue, void* checkdata) : GstBase.DataQueue Required (not null) void* checkdata Required (not null) Returns: GstBase.DataQueue
	drop_head (Number type) : Boolean Pop and unref the head-most GstMiniObject with the given GType. Pop and unref the head-most GstMiniObject with the given GType. Parameters: Number type Required (not null) Returns: Boolean	GstBase.DataQueue
	flush () : none Flushes all the contents of the queue. Flushes all the contents of the queue. Any call to gst_data_queue_push and gst_data_queue_pop will be released. MT safe. Returns: none	GstBase.DataQueue
	get_level (DataQueueSize level) : none Get the current level of the queue. Get the current level of the queue. Parameters: GstBase.DataQueueSize level Required (not null) Returns: none	GstBase.DataQueue
	is_empty () : Boolean Queries if there are any items in the queue. Queries if there are any items in the queue. MT safe. Returns: Boolean	GstBase.DataQueue
	is_full () : Boolean Queries if queue is full. Queries if queue is full. This check will be done using the GstDataQueueCheckFullFunction registered with queue. MT safe. Returns: Boolean	GstBase.DataQueue
	limits_changed () : none Inform the queue that the limits for the fullness check have changed and that any blocking gst_data_queue_push() should be unblocked to recheck the limts. Inform the queue that the limits for the fullness check have changed and that any blocking gst_data_queue_push() should be unblocked to recheck the limts. Returns: none	GstBase.DataQueue
	pop (DataQueueItem item) : Boolean Retrieves the first item available on the queue. Retrieves the first item available on the queue. If the queue is currently empty, the call will block until at least one item is available, OR the MT safe. Parameters: GstBase.DataQueueItem item Required (not null) Returns: Boolean	GstBase.DataQueue
	push (DataQueueItem item) : Boolean Pushes a GstDataQueueItem (or a structure that begins with the same fields) on the queue. Pushes a GstDataQueueItem (or a structure that begins with the same fields) on the queue. If the queue is full, the call will block until space is available, OR the queue is set to flushing state. MT safe. Note that this function has slightly different semantics than gst_pad_push() the GstMiniObject contained in item if the push was successful. If FALSE is returned, the caller is responsible for freeing item and its contents. Parameters: GstBase.DataQueueItem item Required (not null) Returns: Boolean	GstBase.DataQueue
	set_flushing (Boolean flushing) : none Sets the queue to flushing state if flushing is TRUE. Sets the queue to flushing state if flushing is TRUE. If set to flushing state, any incoming data on the queue will be discarded. Any call currently blocking on gst_data_queue_push or gst_data_queue_pop will return straight away with a return value of FALSE. While the queue is in flushing state, all calls to those two functions will return FALSE. MT Safe. Parameters: Boolean flushing Required (not null) Returns: none	GstBase.DataQueue

Events - usage syntax: this.signals.EVENTNAME.connect( Function )

Event		Defined By
	empty (DataQueue self) : none Reports that the queue became empty (empty). Reports that the queue became empty (empty). A queue is empty if the total amount of visible items inside it (num-visible, time, size) is lower than the boundary values which can be set through the GObject properties. Parameters: GstBase.DataQueue self Returns: {none}	GstBase.DataQueue
	full (DataQueue self) : none Reports that the queue became full (full). Reports that the queue became full (full). A queue is full if the total amount of data inside it (num-visible, time, size) is higher than the boundary values which can be set through the GObject properties. Parameters: GstBase.DataQueue self Returns: {none}	GstBase.DataQueue
