public class AttributedGraph extends org.jgrapht.graph.AbstractBaseGraph<AttributedVertex,AttributedEdge>
Basic graph implementation for a directed graph whose vertices and edges support attributes.

The graph can be configured as to how to handle multiple edges with the same source and destination vertices. One option is to simply allow multiple edges. The second option is to collapse duplicate edges such that there is only ever one edge with the same source and destination. In this case, each additional duplicate edge added will cause the edge to have a "Weight" attribute that will be the total number of edges that were added to the same source/destination vertex pair.

    • addVertex

      public AttributedVertex addVertex(String id)
      Adds a new vertex with the given id. The vertex's name will be the same as the id. If a vertex already exists with that id, then that vertex will be returned.
      Parameters:
      id - the unique vertex id that the graph should have a vertex for.
      Returns:
      either an existing vertex with that id, or a newly added vertex with that id
    • addVertex

      public AttributedVertex addVertex(String id, String vertexName)
      Adds a new vertex with the given id and name. If a vertex already exists with that id, then that vertex will be returned, but with its name changed to the given name.
      Parameters:
      id - the unique vertex id that the graph should have a vertex for.
      vertexName - the name to associate with this vertex
      Returns:
      either an existing vertex with that id, or a newly added vertex with that id

    • addEdge

      public AttributedEdge addEdge(AttributedVertex source, AttributedVertex target, String edgeId)
      Creates and adds a new directed edge with the given id between the given source and target vertices. If the graph is set to collapse duplicate edges and an edge for that source and target exists, then the existing edge will be return with its "Weight" attribute set to the total number of edges that have been added between the source and target vertices.
      Parameters:
      source - the source vertex of the directed edge to be created.
      target - the target vertex of the directed edge to be created.
      edgeId - the id to use for the new edge. Note: if this is a duplicate and edges are being collapsed, then this edgeId will not be used.
      Returns:
      a new edge between the source and target if it is the first one or the graph is not collapsing edges. Otherwise, an existing edge with its "Weight" attribute set accordingly.
    • addEdge

      public boolean addEdge(AttributedVertex source, AttributedVertex target, AttributedEdge edge)
      Creates and adds a new directed edge with the given edge object. If the graph is set to collapse duplicate edges and an edge for that source and target exists, then the existing edge will be return with its "Weight" attribute set to the total number of edges that have been added between the source and target vertices.
