Interface DoubleReferencePair<V>

All Superinterfaces:

Pair<java.lang.Double,V>

All Known Implementing Classes:

DoubleReferenceImmutablePair, DoubleReferenceMutablePair

public interface DoubleReferencePair<V>
extends Pair<java.lang.Double,V>

A type-specific Pair; provides some additional methods that use polymorphism to avoid (un)boxing.
