Method Summary

Modifier and Type	Method	Description
boolean	run(Path path1, PathPoint point1, Path path2, PathPoint point2, PathIntersection kind)	Prototype of the callback to iterate through the intersections of two paths.
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, int, java.lang.foreign.MemorySegment) method.
default int	upcall(MemorySegment path1, MemorySegment point1, MemorySegment path2, MemorySegment point2, int kind, MemorySegment userData)	The upcall method is called from native code.

Method Details

run

boolean run(Path path1,
 PathPoint point1,
 Path path2,
 PathPoint point2,
 PathIntersection kind)

Prototype of the callback to iterate through the intersections of two paths.

Since:

4.20

upcall

default int upcall(MemorySegment path1,
 MemorySegment point1,
 MemorySegment path2,
 MemorySegment point2,
 int kind,
 MemorySegment userData)

The upcall method is called from native code. The parameters are marshaled and run(org.gnome.gsk.Path, org.gnome.gsk.PathPoint, org.gnome.gsk.Path, org.gnome.gsk.PathPoint, org.gnome.gsk.PathIntersection) 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, 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
