    • getCallInterface

      default org.lwjgl.system.libffi.FFICIF getCallInterface()
      Specified by:
      getCallInterface in interface org.lwjgl.system.CallbackI

    • callback

      default void callback(long ret, long args)
      Specified by:
      callback in interface org.lwjgl.system.CallbackI

    • invoke

      int invoke(long ufuncs, int a, int b, long ab, long user_data)
      A virtual method for the hb_unicode_funcs_t structure.

      This method should compose a sequence of two input Unicode code points by canonical equivalence, returning the composed code point in a hb_codepoint_t output parameter (if successful). The method must return an hb_bool_t indicating the success of the composition.

      Return value: true is a,b composed, false otherwise

      Parameters:
      ufuncs - a Unicode-functions structure
      a - the first code point to compose
      b - the second code point to compose
      ab - the composed code point
      user_data - user data pointer passed by the caller
