Example 52 with NoRouteToCellException

the class CellStub method addCallback.

/**
 * Registers a callback to be run when the {@code Future}'s computation is {@linkplain
 * java.util.concurrent.Future#isDone() complete} or, if the computation is already complete,
 * immediately.
 *
 * <p>There is no guaranteed ordering of execution of callbacks, but any
 * callback added through this method is guaranteed to be called once the computation is
 * complete.
 *
 * <p>Note: For fast, lightweight listeners that would be safe to execute in
 * any thread, consider {@link MoreExecutors#directExecutor}. For heavier listeners, {@code
 * directExecutor()} carries some caveats. See {@link ListenableFuture#addListener} for
 * details.
 *
 * <p>In is important the the executor isn't blocked by tasks waiting for
 * the callback; such tasks could lead to a deadlock.
 *
 * <p>If not using {@code directExecutor()}, it is advisable to use a
 * CDC preserving executor.
 *
 * @param future   The future attach the callback to.
 * @param callback The callback to invoke when {@code future} is completed.
 * @param executor The executor to run {@code callback} when the future completes.
