public class EqualityDelegateSupport extends java.lang.Object
When the default equals() and hashCode() of a class needs to be overridden for any purpose. An EqualityDelegate can supply an alternate definition for these two methods. The following methods:safeEquals(Object, Object)
,safeHashCode(Object)
should be used in place of the standard methods for equality checks and hash code generation. A specific use of this class provides alternative definitions for serialization purposes (check out: ReferenceTracker)
