Class EqualityDelegateSupport

java.lang.Object

com.inductiveautomation.ignition.common.xmlserialization.serialization.equalitydelegates.EqualityDelegateSupport

public class EqualityDelegateSupport
extends 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)
