HashedMap (The Adobe Experience Manager SDK 2022.11.9850.20221116T162329Z-220900)

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:

java.io.Serializable, java.lang.Cloneable, java.util.Map<K,V>, Get<K,V>, IterableGet<K,V>, IterableMap<K,V>, Put<K,V>
```
public class HashedMap<K,V>
extends AbstractHashedMap<K,V>
implements java.io.Serializable, java.lang.Cloneable
```
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.
