Class VertexPredicateFilter<V,​E>

  • All Implemented Interfaces:
    com.google.common.base.Function<Graph<V,​E>,​Graph<V,​E>>, Filter<V,​E>, java.util.function.Function<Graph<V,​E>,​Graph<V,​E>>

    public class VertexPredicateFilter<V,​E>
    extends java.lang.Object
    implements Filter<V,​E>
    Transforms the input graph into one which contains only those vertices that pass the specified Predicate. The filtered graph is a copy of the original graph (same type, uses the same vertex and edge objects). Only those edges whose entire incident vertex collection passes the predicate are copied into the new graph.
