Class UPool

java.lang.Object
  org.webmacro.util.UPool

All Implemented Interfaces:

Pool

public final class UPool

extends java.lang.Object

implements Pool

This is an unsynchronized object pool. It does synchronize on the objects added to and removed from the pool but it never synchronizes on its own data structures. As a result a null may be returned from the pool when an object actually exists (rare case), but an object is still guaranteed to be returned to only one thread.

Constructor Summary

UPool(int size)
Create a new Pool.

Method Summary

java.lang.Object	get() Get an item from the pool
void	put(java.lang.Object o) Add an item to the pool for later re-use
