Class ReflectiveWorkOnChange

java.lang.Object

org.broadleafcommerce.common.util.ReflectiveWorkOnChange

All Implemented Interfaces:

WorkOnChange

public class ReflectiveWorkOnChange
extends Object
implements WorkOnChange

This WorkOnChange implementation is for a narrow case where the work to be done is simply calling a method on a target object and passing to that method the changed collection. Of course, there must be a method with the correct signature on the target object. This implementation also uses caching to optimize repeat searches for the same method and minimize reflection time.
