Package org.infinispan.commons.util

Class ArrayMap<K,V>

java.lang.Object

java.util.AbstractMap<K,V>

org.infinispan.commons.util.ArrayMap<K,V>

All Implemented Interfaces:

Map<K,V>

Direct Known Subclasses:

HopscotchHashMap

public abstract class ArrayMap<K,V>
extends AbstractMap<K,V>

Base for classes that implement hash map by storing keys in one array and values in another. It assumes that all keys that are in the array are contained in the map and that values are on corresponding indices in the map. Does not support null keys nor values. Forces implementation of methods get(Object), put(Object, Object), remove(Object)
