All Implemented Interfaces:

Expiration<T>

public class CompoundExpiration<T extends Poolable>
extends Object
implements Expiration<T>

Provides a way to compose Expirations.

Given two Expirations, this class considers that a slot is expired if any of the Expiration returns true. This makes it easy to have an Expiration that expires both on time (TimeExpiration) and some other criteria.
