Method Details

run

@Deprecated
Bool run(Font font,
 @Nullable
 @Nullable MemorySegment fontData,
 Codepoint unicode,
 Codepoint variationSelector,
 Codepoint glyph)

Deprecated.

A virtual method for the hb_font_funcs_t of an hb_font_t object.

This method should retrieve the glyph ID for a specified Unicode code point font, with an optional variation selector.

upcall

default int upcall(MemorySegment font,
 MemorySegment fontData,
 int unicode,
 int variationSelector,
 MemorySegment glyph,
 MemorySegment userData)

Deprecated.

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

toCallback

default MemorySegment toCallback(Arena arena)

Deprecated.

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