Interface DoubleReferencePair<V>

All Superinterfaces:
it.unimi.dsi.fastutil.Pair<java.lang.Double,​V>
All Known Implementing Classes:
DoubleReferenceImmutablePair, DoubleReferenceMutablePair
public interface DoubleReferencePair<V>
extends it.unimi.dsi.fastutil.Pair<java.lang.Double,​V>
A type-specific Pair; provides some additional methods that use polymorphism to avoid (un)boxing.
