Method

Description

void

run(TypeClass gClass)

A callback function used by the type system to finalize those portions of a derived types class structure that were setup from the corresponding GBaseInitFunc() function.

default MemorySegment

toCallback(Arena arena)

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

default void

upcall(MemorySegment gClass)

The upcall method is called from native code.

Method Details
- run
  
  void run(TypeClass gClass)
  
  A callback function used by the type system to finalize those portions of a derived types class structure that were setup from the corresponding GBaseInitFunc() function.
  Class finalization basically works the inverse way in which class initialization is performed.
  See GClassInitFunc() for a discussion of the class initialization process.
- upcall
  
  default void upcall(MemorySegment gClass)
  
  The upcall method is called from native code. The parameters are marshaled and run(org.gnome.gobject.TypeClass) is executed.
- toCallback
  
  default MemorySegment toCallback(Arena arena)
  
  Creates a native function pointer to the upcall(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
