Interface ActivityFinder

public interface ActivityFinder

This interface defines facilities that map activity ids to WfActivity objects. ActivityFinders are used (in combination with an identifier) to identify activities in calls to a ResourceAssignmentService. They are guaranteed to be serializable objects with properly implemented equals and hashCode methods. It is expected that resource assignment facilities keep a peristent, indexed record of ActivityFinders and store references to activities as tuples of a finder index and an activity identifier.
