Method Summary

Modifier and Type	Method	Description
Codepoint	run(UnicodeFuncs ufuncs, Codepoint unicode)	A virtual method for the hb_unicode_funcs_t structure.
default MemorySegment	toCallback(Arena arena)	Creates a native function pointer to the upcall(java.lang.foreign.MemorySegment, int, java.lang.foreign.MemorySegment) method.
default int	upcall(MemorySegment ufuncs, int unicode, MemorySegment userData)	The upcall method is called from native code.

Method Details

run

Codepoint run(UnicodeFuncs ufuncs,
 Codepoint unicode)

A virtual method for the hb_unicode_funcs_t structure.

This method should retrieve the Bi-Directional Mirroring Glyph code point for a specified Unicode code point.

<note>Note: If a code point does not have a specified Bi-Directional Mirroring Glyph defined, the method should return the original code point.</note>

upcall

default int upcall(MemorySegment ufuncs,
 int unicode,
 MemorySegment userData)

The upcall method is called from native code. The parameters are marshaled and run(org.freedesktop.harfbuzz.UnicodeFuncs, org.freedesktop.harfbuzz.Codepoint) is executed.

toCallback

default MemorySegment toCallback(Arena arena)

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