Class PartitionedWeakHashMap

java.lang.Object
  java.util.AbstractMap
      org.jboss.serial.util.PartitionedWeakHashMap

All Implemented Interfaces:

java.util.Map

public class PartitionedWeakHashMap
extends java.util.AbstractMap

This is a WeakHashMap divided into partitions, using a simple algorithm of using the hashCode of a Key % numberOfPartitions to determine what partition to use. This is intended to minimize synchroniozation affects
