All Implemented Interfaces:

com.webobjects.eocontrol.EOKeyValueArchiving, java.io.Serializable

public class ERDDelayedRuleAssignment
extends ERDDelayedAssignment

DelayedRuleAssignment expects an array of rules as its value. The rules are evaluated in turn until one returns a non-null result. This is done every time that the propertyKey is requested thus making the rule system a lot more dynamic.
