Method Details

run

UnicodeGeneralCategory run(UnicodeFuncs ufuncs,
 Codepoint unicode)

A virtual method for the hb_unicode_funcs_t structure.

This method should retrieve the General Category property for a specified Unicode code point.

Parameters:

ufuncs - A Unicode-functions structure

unicode - The code point to query

Returns:

The hb_unicode_general_category_t of unicode

upcall

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

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

toCallback

default MemorySegment toCallback(Arena arena)

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

Specified by:

toCallback in interface FunctionPointer

Parameters:

arena - the arena in which the function pointer is allocated
