Examples of com.google.gwt.dev.cfg.ModuleDef$LibraryDependencyEdge

com.google.gwt.dev.cfg.ModuleDef
Encapsulates two String names which conceptually represent the starting and ending points of a path.
For example in the following module dependency path ["com.acme.MyApp", "com.acme.widgets.Widgets", "com.google.gwt.user.User"] the fromName is "com.acme.MyApp" and the toName is "com.google.gwt.user.User" and together they form a PathEndNames instance.
The purpose of the class is to serve as a key by which to lookup the fileset path that connects two libraries. It makes it possible to insert fileset entries into a circular module reference report.
