default void	upcall(MemorySegment data, MemorySegment object, int isLastRef)	The upcall method is called from native code.

Method Details

run

void run(@Nullable MemorySegment data,
 GObject object,
 boolean isLastRef)

A callback function used for notification when the state of a toggle reference changes.

data - Callback data passed to g_object_add_toggle_ref()

object - The object on which g_object_add_toggle_ref() was called.

isLastRef - true if the toggle reference is now the last reference to the object. false if the toggle reference was the last reference and there are now other references.

upcall

default void upcall(MemorySegment data,
 MemorySegment object,
 int isLastRef)

The upcall method is called from native code. The parameters are marshaled and run(MemorySegment, GObject, boolean) is executed.

toCallback

default MemorySegment toCallback(Arena arena)

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