Method Summary

Modifier and Type	Method	Description
MemorySegment	run(Memory mem, MapInfo info, long maxsize)	Get the memory of mem that can be accessed according to the mode specified in info's flags.
default MemorySegment	toCallback(Arena arena)	Creates a native function pointer to the upcall(java.lang.foreign.MemorySegment, java.lang.foreign.MemorySegment, long) method.
default MemorySegment	upcall(MemorySegment mem, MemorySegment info, long maxsize)	The upcall method is called from native code.

Method Details

run

MemorySegment run(Memory mem,
 MapInfo info,
 long maxsize)

Get the memory of mem that can be accessed according to the mode specified in info's flags. The function should return a pointer that contains at least maxsize bytes.

upcall

default MemorySegment upcall(MemorySegment mem,
 MemorySegment info,
 long maxsize)

The upcall method is called from native code. The parameters are marshaled and run(org.freedesktop.gstreamer.gst.Memory, org.freedesktop.gstreamer.gst.MapInfo, long) is executed.

toCallback

default MemorySegment toCallback(Arena arena)

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

Specified by:

toCallback in interface FunctionPointer

Parameters:

arena - the arena in which the function pointer is allocated
