Class PairMap<T,I,V>

java.lang.Object

java.util.AbstractMap<Pair<T,I>,V>

it.uniroma3.mat.extendedset.wrappers.matrix.PairMap<T,I,V>

All Implemented Interfaces:

Serializable, Cloneable, Map<Pair<T,I>,V>

public class PairMap<T,I,V>
extends AbstractMap<Pair<T,I>,V>
implements Serializable, Cloneable

An class that associates a value to each pair within a PairSet instance. It is not as fast as HashMap , but requires much less memory.

Constructor Detail

PairMap

public PairMap(PairSet<T,I> keys)
