Class LimitedDurationDispatcher

java.lang.Object

org.dspace.checker.LimitedDurationDispatcher

All Implemented Interfaces:

BitstreamDispatcher

public class LimitedDurationDispatcher
extends Object
implements BitstreamDispatcher

A delegating dispatcher that puts a time limit on the operation of another dispatcher.

Unit testing this class would be possible by abstracting the system time into an abstract clock. We decided this was not worth the candle.
