[jgrapht-users] remove all edges and vertices

[Alex M. <am...@di...>]

Does anyone know a way to reset an entire graph?  I tried the following
methods and in all cases I got a ConcurrentModificationException.

 

Attempt #1

     graph.removeAllEdges( graph.edgeSet() );

     graph.removeAllVertices( graph.vertexSet() );

 

Attempt #2

      Set<RelationshipEdge> allEdges = graph.edgeSet();

     for ( RelationshipEdge aEdge : allEdges )

      { 

         graph.removeEdge( aEdge );

      }

 

Attempt #3

      Set<RelationshipEdge> allEdges = graph.edgeSet();

      allEdges.clear();

 

 

Thanks,

Alex
