Class SimpleMap<K,V>

java.lang.Object

java.util.AbstractMap<K,V>

org.apache.juneau.internal.SimpleMap<K,V>

Type Parameters:

K - The key type.

V - The value type.

All Implemented Interfaces:

Map<K,V>

public final class SimpleMap<K,V>
extends AbstractMap<K,V>

An instance of a Map where the keys and values are simple arrays.

Typically more efficient than HashMaps for small maps (e.g. <10 entries).

Does not support adding or removing entries.

Setting values overwrites the value on the underlying value array.
