Class DefaultSorter  

java.lang.Object
  org.objectstyle.cayenne.access.util.DefaultSorter

All Implemented Interfaces:

DependencySorter

---

public class DefaultSorter

extends java.lang.Object

implements DependencySorter

DefaultSorter is a default implementation of DependencySorter based on ASHWOOD library. Presently it works for acyclic database schemas with possible multi-reflexive tables. The class uses topological sorting from ASHWOOD.
