Class PartialProject

java.lang.Object
  org.apache.cayenne.project.Project
      org.apache.cayenne.project.PartialProject

public class PartialProject
extends Project

PartialProject is a "lightweight" project implementation. It can work with projects even when some of the resources are missing. It never instantiates Cayenne stack objects, using other, lightweight, data structures instead.
