Class HashedMap<K,V> 
java.lang.Object
java.util.AbstractMap<K,V>
 
org.apache.commons.collections4.map.AbstractHashedMap<K,V>
 
org.apache.commons.collections4.map.HashedMap<K,V> 
- Type Parameters:
- K- the type of the keys in this map
- V- the type of the values in this map
- All Implemented Interfaces:
- Serializable,- Cloneable,- Map<K,,- V> - Get<K,,- V> - IterableGet<K,,- V> - IterableMap<K,,- V> - Put<K,- V> 
A 
Map implementation that is a general purpose alternative
 to HashMap.
 
 This implementation improves on the JDK1.4 HashMap by adding the
 MapIterator
 functionality and many methods for subclassing.
 
 Note that HashedMap is not synchronized and is not thread-safe.
 If you wish to use this map from multiple threads concurrently, you must use
 appropriate synchronization. The simplest approach is to wrap this map
 using Collections.synchronizedMap(Map). This class may throw
 exceptions when accessed by concurrent threads without synchronization.
