public class PredicatedParallelEdgeIndexFunction<V,E> extends java.lang.Object implements edu.uci.ics.jung.graph.util.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

getInstance
public static <V,E> PredicatedParallelEdgeIndexFunction<V,E> getInstance()
-
getIndex
public int getIndex(edu.uci.ics.jung.graph.Graph<V,E> graph, E e)
Returns the index for the specified edge. Calculates the indices fore
and for all edges parallel toe
.
-
getPredicate
public org.apache.commons.collections4.Predicate<E> getPredicate()
- Returns:
- the predicate
-
setPredicate
public void setPredicate(org.apache.commons.collections4.Predicate<E> predicate)
- Parameters:
predicate
- the predicate to set
-
reset
public void reset(edu.uci.ics.jung.graph.Graph<V,E> graph, E e)
Resets the indices for this edge and its parallel edges. Should be invoked when an edge parallel toe
has been added or removed.
