Interface PolicyCondition

All Superinterfaces:

java.io.Serializable

public interface PolicyCondition
extends java.io.Serializable

This class stipulates a condition for the execution of a Policy. A policy can be executed on successful satisfaction of a condition. This interface has been introduced to enable the execution of a policy when it satisfies a given set of conditions. When the condtion is satisfied the corressponding action is invoked/called (the PolicyAction). The condition and its corresponding action share a common key. This key (a unique string)helps identify/correlate a condition to an action. Thus, a(time,condition) can now be specified to execute policy. The use of PolicyCondition interface and PolicyAction interface helps in handling the condition and action separately,if required.
