Package org.infinispan.commons.util

Class AbstractMap<K,V>

java.lang.Object

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

All Implemented Interfaces:

Map<K,V>

Direct Known Subclasses:

EquivalentHashMap, FastCopyHashMap

public abstract class AbstractMap<K,V>
extends Object
implements Map<K,V>

Similar to the JDK's AbstractMap, this provides common functionality for custom map implementations. Unlike JDK's AbstractMap, there is no support for null keys.

Since:

4.0
