Method Summary

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

Method Details

run

@Deprecated
int run(UnicodeFuncs ufuncs,
 Codepoint u,
 Codepoint decomposed)

Deprecated.

Fully decompose u to its Unicode compatibility decomposition. The codepoints of the decomposition will be written to decomposed. The complete length of the decomposition will be returned.

If u has no compatibility decomposition, zero should be returned.

The Unicode standard guarantees that a buffer of length HB_UNICODE_MAX_DECOMPOSITION_LEN codepoints will always be sufficient for any compatibility decomposition plus an terminating value of 0. Consequently, decompose must be allocated by the caller to be at least this length. Implementations of this function type must ensure that they do not write past the provided array.

upcall

default int upcall(MemorySegment ufuncs,
 int u,
 MemorySegment decomposed,
 MemorySegment userData)

Deprecated.

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