Class WeightedUnmodifiableSet<E>

  • Type Parameters:
    E - element type
    All Implemented Interfaces:
    java.io.Serializable, java.lang.Iterable<E>, java.util.Collection<E>, java.util.Set<E>
    Direct Known Subclasses:
    CliqueAlgorithm.CliqueImpl, IndependentSetAlgorithm.IndependentSetImpl, SpannerAlgorithm.SpannerImpl, VertexCoverAlgorithm.VertexCoverImpl
    public class WeightedUnmodifiableSet<E>
extends java.util.AbstractSet<E>
implements java.io.Serializable
    Implementation of a weighted, unmodifiable set. This class can for instance be used to store a weighted vertex cover. The hashCode() and equals() methods are identical to those of a normal set, i.e. they are independent of the weight of this class. All methods are delegated to the underlying set.
