Class AbstractMap<K,V>

java.lang.Object

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

All Implemented Interfaces:

java.util.Map<K,V>

Direct Known Subclasses:

EquivalentHashMap, FastCopyHashMap

public abstract class AbstractMap<K,V>
extends java.lang.Object
implements java.util.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.
