    • invoke

      int invoke(long buffer, long font, long message, long user_data)
      A callback method for hb_buffer_t. The method gets called with the hb_buffer_t it was set on, the hb_font_t the buffer is shaped with and a message describing what step of the shaping process will be performed. Returning false from this method will skip this shaping step and move to the next one.

      Return value: true to perform the shaping step, false to skip it.

      Parameters:
      buffer - an hb_buffer_t to work upon
      font - the hb_font_t the buffer is shaped with
      message - NULL-terminated message passed to the function
