Method Summary

Modifier and Type	Method	Description
void	run(DrawFuncs dfuncs, @Nullable MemorySegment drawData, DrawState st)	A virtual method for the hb_draw_funcs_t to perform a "close-path" draw operation.
default MemorySegment	toCallback(Arena arena)	Creates a native function pointer to the upcall(java.lang.foreign.MemorySegment, java.lang.foreign.MemorySegment, java.lang.foreign.MemorySegment, java.lang.foreign.MemorySegment) method.
default void	upcall(MemorySegment dfuncs, MemorySegment drawData, MemorySegment st, MemorySegment userData)	The upcall method is called from native code.

Method Details

run

void run(DrawFuncs dfuncs,
 @Nullable
 @Nullable MemorySegment drawData,
 DrawState st)

A virtual method for the hb_draw_funcs_t to perform a "close-path" draw operation.

upcall

default void upcall(MemorySegment dfuncs,
 MemorySegment drawData,
 MemorySegment st,
 MemorySegment userData)

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

toCallback

default MemorySegment toCallback(Arena arena)

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