Method Summary

Modifier and Type	Method	Description
boolean	run(@Nullable MemorySegment context, @Nullable byte @Nullable [] buf)	Incrementally loads a buffer into the image data.
default MemorySegment	toCallback(Arena arena)	Creates a native function pointer to the upcall(MemorySegment, MemorySegment, int, MemorySegment) method.
default int	upcall(MemorySegment context, MemorySegment buf, int size, MemorySegment _gerrorPointer)	The upcall method is called from native code.

Method Details

run

boolean run(@Nullable MemorySegment context,
 @Nullable byte @Nullable [] buf)
     throws GErrorException

Incrementally loads a buffer into the image data.

Parameters:

context - the state object created by GdkPixbuf.PixbufModuleBeginLoadFunc

buf - the data to load

Returns:

TRUE if the incremental load was successful

Throws:

GErrorException - see GError

upcall

default int upcall(MemorySegment context,
 MemorySegment buf,
 int size,
 MemorySegment _gerrorPointer)

The upcall method is called from native code. The parameters are marshaled and run(MemorySegment, byte[]) is executed.

toCallback

default MemorySegment toCallback(Arena arena)

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

Specified by:

toCallback in interface FunctionPointer

Parameters:

arena - the arena in which the function pointer is allocated

Returns:

the native function pointer
