Method Detail

get

R get()
      throws GridClientException

Synchronously waits for completion and returns result.

Returns:

Completed future result.

Throws:

GridClientException - In case of error.

      throws GridClientException

Synchronously waits for completion and returns result.

Parameters:

timeout - Timeout interval to wait future completes.

unit - Timeout interval unit to wait future completes.

Returns:

Completed future result.

Throws:

GridClientException - In case of error.

GridClientFutureTimeoutException - If timed out before future finishes.

isDone

boolean isDone()

Checks if future is done.

Returns:

Whether future is done.

listenAsync

void listenAsync(GridClientFutureListener<R>... lsnrs)

Parameters:

lsnrs - Listeners to be registered.

stopListenAsync

void stopListenAsync(GridClientFutureListener<R>... lsnrs)

Removes listeners registered before.

Parameters:

lsnrs - Listeners to be removed.
