Class MCRDelayedRunnable

java.lang.Object

org.mycore.util.concurrent.MCRDelayedRunnable

All Implemented Interfaces:

Comparable<Delayed>, Runnable, Delayed, MCRDecorator<Runnable>

public class MCRDelayedRunnable
extends Object
implements Delayed, Runnable, MCRDecorator<Runnable>

Encapsulates a Runnable with in a object that can be fed into a DelayQueue Note: This class has a natural ordering that is inconsistent with equals. Note: Two objects of this class are equal, if their ids are equal (other properties are ignored).
