Examples of HierarchicalGraph

org.gephi.graph.api.HierarchicalGraph
Implementation of graphs within graphs concept, by proposing methods to manipulate the hierarchy of nodes.
The hierarchical graph maintains a tree of all nodes, it's the hierarchy and a in-view flag for each. Note that 'view' means something else than for GraphView.
A node in the hierarchy view means it is visible and none of its ancestors or descendants are. If this node is expanded, it's children become 'in-view'. If it is retracted, its parent becomes 'in-view'. The hierarchy view can be modified with expand(), retract(), resetViewToLeaves(), resetViewToTopNodes() and resetViewToLevel(). Note that the nodes and edges returns by getNodes() or getEdges() use only nodes in the current view. To get all nodes in the hierarchy, see getNodesTree(). @author Mathieu Bastian @see GraphModel
