Method Details

run

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

The prototype of the function used to inform the queue that it should be considered as 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(org.freedesktop.gstreamer.base.DataQueue, int, int, long, java.lang.foreign.MemorySegment) is executed.

toCallback

default MemorySegment toCallback(Arena arena)

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

Specified by:

toCallback in interface FunctionPointer

Parameters:

arena - the function pointer will be allocated in this arena

Returns:

the native function pointer
