Interface Graph

All Known Subinterfaces:

RootGraph, Subgraph

public interface Graph

The Graph interface is implemented by all objects which support to add a graph structure. The are methods to add nodes, edges and subgraphs. For convenience there are also some methods to define default design for those types. The default is used if you add, for example a node, without parameter.
