public class ObjectIdentityImpl extends Object implements ObjectIdentity
AclObjectIdentity
.
Uses String
s to store the identity of the domain object instance. Also offers a constructor that uses
reflection to build the identity information.

method, otherwise an exception will be thrown. The object passed will
be considered the javaType

an alternate constructor should be used instead.object

.Because ACLs are largely immutable, it is strongly recommended to use a synthetic identifier (such as a database sequence number for the primary key). Do not use an identifier with business meaning, as that business meaning may change.
