public static void addPending(Future<?> future)

Register a pending Future that has a callback.

Parameters:

future - must have at least one callback

removePending

public static void removePending(Future<?> future)

Deregister a pending Future that had a callback.

completeAllPendingFutures

public static void completeAllPendingFutures()
