Class JavaClass::Dependencies::GraphmlSerializer
In: lib/javaclass/dependencies/graphml_serializer.rb
Parent: Object

Serializes a Graph of Node to GraphML (XML). To see the graph, use yED, www.yworks.com/en/products_yed_about.html to

  • load the graphml file.
  • Then select all nodes and apply Tools/Fit Node to Label.
  • Finally apply the Layout/Hierarchical or maybe Layout/Organic/Smart.
