Class PartitionedWeakHashMap

java.lang.Object

java.util.AbstractMap

com.ovea.jetty.session.serializer.jboss.serial.util.PartitionedWeakHashMap

All Implemented Interfaces:

Map

public class PartitionedWeakHashMap
extends 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
