Method Summary

Modifier and Type	Method	Description
boolean	run(DataQueue queue, int visible, int bytes, long time, @Nullable MemorySegment checkdata)	The prototype of the function used to inform the queue that it should be considered as full.
default MemorySegment	toCallback(Arena arena)	Creates a native function pointer to the upcall(MemorySegment, int, int, long, MemorySegment) method.
default int	upcall(MemorySegment queue, int visible, int bytes, long time, MemorySegment checkdata)	The upcall method is called from native code.

Method Details

run

boolean run(DataQueue queue,
 int visible,
 int bytes,
 long time,
 @Nullable MemorySegment checkdata)

The prototype of the function used to inform the queue that it should be considered as full.

Parameters:

queue - a GstDataQueue.

visible - The number of visible items currently in the queue.

bytes - The amount of bytes currently in the queue.

time - The accumulated duration of the items currently in the queue.

checkdata - The gpointer registered when the GstDataQueue was created.

Returns:

true if the queue should be considered full.

upcall

default int upcall(MemorySegment queue,
 int visible,
 int bytes,
 long time,
 MemorySegment checkdata)

The upcall method is called from native code. The parameters are marshaled and run(DataQueue, int, int, long, MemorySegment) is executed.

toCallback

default MemorySegment toCallback(Arena arena)

Creates a native function pointer to the upcall(MemorySegment, int, int, long, MemorySegment) method.

Specified by:

toCallback in interface FunctionPointer

Parameters:

arena - the arena in which the function pointer is allocated

Returns:

the native function pointer
