Class PredicatedParallelEdgeIndexFunction<V,E>

java.lang.Object
edu.uci.ics.jung.visualization.util.PredicatedParallelEdgeIndexFunction<V,E>
All Implemented Interfaces:
EdgeIndexFunction<V,E>
public class PredicatedParallelEdgeIndexFunction<V,E> extends Object implements EdgeIndexFunction<V,E>
A class which creates and maintains indices for parallel edges. Edges are evaluated by a Predicate function and those that evaluate to true are excluded from computing a parallel offset

  • Field Details

    • edge_index

      protected Map<E,Integer> edge_index

    • predicate

      protected com.google.common.base.Predicate<E> predicate

  • Constructor Details

    • PredicatedParallelEdgeIndexFunction

      private PredicatedParallelEdgeIndexFunction()
      Parameters:
      graph - the graph with respect to which the index is calculated

  • Method Details

    • getInstance

      public static <V,E> PredicatedParallelEdgeIndexFunction<V,E> getInstance()

    • getIndex

      public int getIndex(Graph<V,E> graph, E e)
      Returns the index for the specified edge. Calculates the indices for e and for all edges parallel to e.
      Specified by:
      getIndex in interface EdgeIndexFunction<V,E>
      Parameters:
      graph - the graph with respect to which the index is calculated
      e - the edge whose index is to be calculated
      Returns:
      the index of the edge with respect to this index function

    • getIndex

      protected int getIndex(Graph<V,E> graph, E e, V v)

    • getPredicate

      public com.google.common.base.Predicate<E> getPredicate()

    • setPredicate

      public void setPredicate(com.google.common.base.Predicate<E> predicate)

    • reset

      public void reset(Graph<V,E> graph, E e)
      Resets the indices for this edge and its parallel edges. Should be invoked when an edge parallel to e has been added or removed in this graph.
      Specified by:
      reset in interface EdgeIndexFunction<V,E>
      Parameters:
      graph - the graph with respect to which the index is calculated
      e - the edge whose indices are to be reset for graph

    • reset

      public void reset()
      Clears all edge indices for all edges in all graphs. Does not recalculate the indices.
      Specified by:
      reset in interface EdgeIndexFunction<V,E>
