Class CacheKey

java.lang.Object
  |
  +--org.jboss.ejb.CacheKey

All Implemented Interfaces:

java.io.Externalizable, java.io.Serializable

Direct Known Subclasses:

FastKey

public class CacheKey

extends java.lang.Object

implements java.io.Externalizable

CacheKey CacheKey is an encapsulation of both the PrimaryKey and a cache specific key This implementation is a safe implementation in the sense that it doesn't rely on the user supplied hashcode and equals. It is also fast since the hashCode operation is pre-calculated.
