Class SoftCache<K,V>

java.lang.Object

java.util.AbstractMap<K,V>

org.cristalise.kernel.utils.SoftCache<K,V>

Type Parameters:

K - key

V - value

All Implemented Interfaces:

Map<K,V>

public class SoftCache<K,V>
extends AbstractMap<K,V>

SoftReferences are reaped if no strong references are left and the vm is running out of memory. Most caches in the kernel use this.
