Overview

This class is part of a private API. You should avoid using this class if possible, as it may be removed or be changed in the future.

This is Puppet's class for modeling edges in its configuration graph. It used to be a subclass of GRATR::Edge, but that class has weird hash overrides that dramatically slow down the graphing.
