Class PairLists.MapPairList<T,U>

java.lang.Object

java.util.AbstractCollection<Map.Entry<T,U>>

java.util.AbstractList<Map.Entry<T,U>>

net.hydromatic.morel.util.PairLists.AbstractPairList<T,U>

net.hydromatic.morel.util.PairLists.MapPairList<T,U>

Type Parameters:

T - First type

U - Second type

All Implemented Interfaces:

Iterable<Map.Entry<T,U>>, Collection<Map.Entry<T,U>>, List<Map.Entry<T,U>>, SequencedCollection<Map.Entry<T,U>>, PairList<T,U>

Enclosing class:

PairLists

static class PairLists.MapPairList<T,U>
extends PairLists.AbstractPairList<T,U>

List of pairs backed by a map.

It works for all maps, but is efficient only if ImmutableList.copyOf(Iterable) on the key-set and value-set are O(0). Therefore, we recommend using it only with maps that extend ImmutableMap.
