  • Method Details

    • run

      void run(GError error)

      Specifies the type of function which is called just after an extended error instance is created and its fields filled. It should only initialize the fields in the private data, which can be received with the generated *_get_private() function.

      Normally, it is better to use G_DEFINE_EXTENDED_ERROR(), as it already takes care of getting the private data from error.

      Parameters:
      error - extended error

    • upcall

      default void upcall(MemorySegment error)
      The upcall method is called from native code. The parameters are marshaled and run(GError) is executed.

    • toCallback

      default MemorySegment toCallback(Arena arena)
      Creates a native function pointer to the upcall(MemorySegment) method.
      Specified by:
      toCallback in interface FunctionPointer
      Parameters:
      arena - the arena in which the function pointer is allocated
      Returns:
      the native function pointer
