Interface AclObjectIdentity

All Superinterfaces:: java.io.Serializable

All Known Implementing Classes:: NamedEntityObjectIdentity

public interface AclObjectIdentity
extends java.io.Serializable

Interface representing the identity of an individual domain object instance.

It should be noted that AclObjectIdentity instances are created in various locations throughout the package. As AclObjectIdentitys are used as the key for caching, it is essential that implementations provide methods so that object-equality rather than reference-equality can be relied upon by caches. In other words, a cache can consider two AclObjectIdentitys equal if identity1.equals(identity2), rather than reference-equality of identity1==identity2.

In practical terms this means you must implement the standard java.lang.Object methods shown below. Depending on your cache's internal structure, you may also need to implement special interfaces such as java.util.Comparator or java.lang.Comparable.
