Class TransitiveMap<K,V2>

java.lang.Object

com.google.common.collect.ForwardingObject

com.google.common.collect.ForwardingMap<K,V2>

org.tenidwa.collections.utils.TransitiveMap<K,V2>

All Implemented Interfaces:

Map<K,V2>

public final class TransitiveMap<K,V2>
extends com.google.common.collect.ForwardingMap<K,V2>

A map that retains keys of the original map, but whose values are a function of key/value pairs from the original map.

Original map maps k to v.
Transitive map maps k to f(k, v).

     new TransitiveMap(
       ImmutableMap.of(
         "dude", 4,
         "man", 3
       ),
       (k, v) -> new Placard(k ,v)
     ); // { "dude" -> Placard("dude", 4), "man" -> Placard("man", 3) }
