Module: DOT

Defined in:

lib/puppet/external/dot.rb

Overview

rdot.rb

This is a modified version of dot.rb from Dave Thomas’s rdoc project. I [Horst Duchene] renamed it to rdot.rb to avoid collision with an installed rdoc/dot.

It also supports undirected edges.

Defined Under Namespace

Classes: DOTDigraph, DOTDirectedEdge, DOTEdge, DOTElement, DOTNode, DOTPort, DOTSimpleElement, DOTSubgraph
