Class GenericKeyedObjectPool.ObjectTimestampPair<T>

  • All Implemented Interfaces:
    java.lang.Comparable<T>
    Enclosing class:
    GenericKeyedObjectPool<K,​V>
    static class GenericKeyedObjectPool.ObjectTimestampPair<T>
extends java.lang.Object
implements java.lang.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.
