default int	upcall(MemorySegment sourceAppSrc, long offset)	The upcall method is called from native code.

Method Details

run

boolean run(long offset)

Seek to the given offset. The next push-buffer should produce buffers from the new offset. This callback is only called for seekable stream types.

upcall

default int upcall(MemorySegment sourceAppSrc,
 long offset)

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

toCallback

default MemorySegment toCallback(Arena arena)

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