    • dispatchSuccess

      public static <T> void dispatchSuccess(SuccessCallback<T> success, T arg)

      Calls the given callback's Callback#onSucess(java.lang.Object) method, passing the supplied arg as a parameter. This method guarantees that onSuccess() will be called on the EDT. If it is already running on the EDT, it will just call it directly. Otherwise it will wrap it in Display#callSerially(java.lang.Runnable).

      Parameters

      • The: type of the callback.

      • success: The success callback to be called.

      • arg: The argument to pass to the success callback.

    • dispatchError

      public static void dispatchError(FailureCallback failure, Throwable error)

      Calls the given callback's java.lang.Throwable, int, java.lang.String) method, passing the supplied error as a parameter. This method guarantees that onError() will be called on the EDT. If it is already running on the EDT, it will just call it directly. Otherwise it will wrap it in Display#callSerially(java.lang.Runnable).

      Parameters

      • failure: The failure callback to be called.

      • error: The error to pass to the callback

    • run

      public void run()
      Description copied from interface: Runnable
      When an object implementing interface Runnable is used to create a thread, starting the thread causes the object's run method to be called in that separately executing thread. The general contract of the method run is that it may take any action whatsoever.
      Specified by:
      run in interface Runnable
