Class Relation<K,V>

java.lang.Object

org.graalvm.shadowed.com.ibm.icu.impl.Relation<K,V>

All Implemented Interfaces:

Cloneable, Freezable<Relation<K,V>>

public class Relation<K,V>
extends Object
implements Freezable<Relation<K,V>>

A Relation is a set of mappings from keys to values. Unlike Map, there is not guaranteed to be a single value per key. The Map-like APIs return collections for values.
