Examples of JGraphHierarchyModel

com.jgraph.layout.hierarchical.model.JGraphHierarchyModel
Internal model of a hierarchical graph. This model stores nodes and edges equivalent to the real graph nodes and edges, but also stores the rank of the cells, the order within the ranks and the new candidate locations of cells. The internal model also reverses edge direction were appropriate , ignores self-loop and groups parallels together under one edge object.
