public interface AclObjectIdentity extends java.io.Serializable
It should be noted that AclObjectIdentity
instances are created
in various locations throughout the package. As
AclObjectIdentity
s 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 AclObjectIdentity
s 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
.
