Method Details

run

boolean run(long deadline)

This function is called incrementally to process additional background work. A deadline is provided which can be checked using GLib.getMonotonicTime() so that additional work can be processed each frame.

This is useful for situations where you are incrementally performing background work such as spell checking or semantic syntax highlighting.

upcall

default int upcall(long deadline,
 MemorySegment userData)

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

toCallback

default MemorySegment toCallback(Arena arena)

Creates a native function pointer to the upcall(long, java.lang.foreign.MemorySegment) method.

Specified by:

Parameters:

arena - the function pointer will be allocated in this arena

Returns:

the native function pointer
