Method Summary

Modifier and Type	Method	Description
void	run(PaintFuncs funcs, @Nullable MemorySegment paintData, PaintCompositeMode mode)	A virtual method for the hb_paint_funcs_t to undo the effect of a prior call to the hb_paint_funcs_push_group_func_t vfunc.
default MemorySegment	toCallback(Arena arena)	Creates a native function pointer to the upcall(java.lang.foreign.MemorySegment, java.lang.foreign.MemorySegment, int, java.lang.foreign.MemorySegment) method.
default void	upcall(MemorySegment funcs, MemorySegment paintData, int mode, MemorySegment userData)	The upcall method is called from native code.

Method Details

run

void run(PaintFuncs funcs,
 @Nullable MemorySegment paintData,
 PaintCompositeMode mode)

A virtual method for the hb_paint_funcs_t to undo the effect of a prior call to the hb_paint_funcs_push_group_func_t vfunc.

This call stops the redirection to the intermediate surface, and then composites it on the previous surface, using the compositing mode passed to this call.

Since:

7.0.0

upcall

default void upcall(MemorySegment funcs,
 MemorySegment paintData,
 int mode,
 MemorySegment userData)

The upcall method is called from native code. The parameters are marshaled and run(org.freedesktop.harfbuzz.PaintFuncs, java.lang.foreign.MemorySegment, org.freedesktop.harfbuzz.PaintCompositeMode) is executed.

toCallback

default MemorySegment toCallback(Arena arena)

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

Specified by:

toCallback in interface FunctionPointer

Parameters:

arena - the arena in which the function pointer is allocated

Returns:

the native function pointer
