com.google.devtools.depan.model.GraphModel
Main Graph implementation. Also implements GraphBuilder, so it takes care of building the graph. This class handle all the operations related to the Graph itself. A graph is like a transition matrix (even it is not stored like that). it stores a list of nodes, and a list of edges. It also offers convenient methods to look for a node, an edge, successors and predecessors of a node given a set of relations, roots of the graph. Finally, it maintains a list of views opened for this graph, so we can apply binary operations on views easily. Node that any inserted node in the graph should be involved in at least one edge. Otherwise, it will not be saved by PersistentGraph. @author ycoppel@google.com (Yohann Coppel)
