Method Details

run

@Deprecated
void run(Font font,
 @Nullable MemorySegment fontData,
 Codepoint glyph,
 DrawFuncs drawFuncs,
 @Nullable MemorySegment drawData)

Deprecated.

Use hb_font_draw_glyph_func_t instead

A virtual method for the hb_font_funcs_t of an hb_font_t object.

Parameters:

font - hb_font_t to work upon

fontData - font user data pointer

glyph - The glyph ID to query

drawFuncs - The draw functions to send the shape data to

drawData - The data accompanying the draw functions

Since:

4.0.0

upcall

default void upcall(MemorySegment font,
 MemorySegment fontData,
 int glyph,
 MemorySegment drawFuncs,
 MemorySegment drawData,
 MemorySegment userData)

Deprecated.

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

toCallback

default MemorySegment toCallback(Arena arena)

Deprecated.

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

Specified by:

toCallback in interface FunctionPointer

Parameters:

arena - the arena in which the function pointer is allocated

Returns:

the native function pointer
