Method Detail

relabelEdge

public static Edge relabelEdge(Graph graph,
               Edge oldEdge,
               Object newId,
               String newLabel)

An edge is relabeled by creating a new edge with the same properties, but new label. Note that an edge is deleted and an edge is added.

Parameters:

graph - the graph to add the new edge to

oldEdge - the existing edge to "relabel"

newId - the id of the new edge

newLabel - the label of the new edge

Returns:

the newly created edge

relabelEdges

public static void relabelEdges(Graph graph,
                Iterable<Edge> oldEdges,
                String newLabel)

Edges are relabeled by creating new edges with the same properties, but new label. Note that for each edge is deleted and an edge is added.

Parameters:

graph - the graph to add the new edge to

oldEdges - the existing edges to "relabel"

newLabel - the label of the new edge

getOther

public static Vertex getOther(Edge edge,
              Vertex vertex)
