Class GenericKeyedObjectPool.ObjectTimestampPair<T>

java.lang.Object
org.apache.commons.pool.impl.GenericKeyedObjectPool.ObjectTimestampPair<T>
All Implemented Interfaces:
Comparable<T>
Enclosing class:
GenericKeyedObjectPool<K,V>
static class GenericKeyedObjectPool.ObjectTimestampPair<T> extends Object implements Comparable<T>
A simple "struct" encapsulating an object instance and a timestamp. Implements Comparable, objects are sorted from old to new. This is also used by GenericObjectPool.
