Method Summary

Modifier and Type	Method	Description
boolean	run(MiniObject obj)	Function prototype for when a miniobject has lost its last refcount.
default MemorySegment	toCallback(Arena arena)	Creates a native function pointer to the upcall(java.lang.foreign.MemorySegment) method.
default int	upcall(MemorySegment obj)	The upcall method is called from native code.

Method Details

run

boolean run(MiniObject obj)

Function prototype for when a miniobject has lost its last refcount. Implementation of the mini object are allowed to revive the passed object by doing a gst_mini_object_ref(). If the object is not revived after the dispose function, the function should return true and the memory associated with the object is freed.

upcall

default int upcall(MemorySegment obj)

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

toCallback

default MemorySegment toCallback(Arena arena)

Creates a native function pointer to the upcall(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
