TiedMapEntry (Apache Commons Collections 4.0 API)

java.lang.Object
- org.apache.commons.collections4.keyvalue.TiedMapEntry<K,V>

All Implemented Interfaces:

Serializable, Map.Entry<K,V>, KeyValue<K,V>
```
public class TiedMapEntry<K,V>
extends Object
implements Map.Entry<K,V>, KeyValue<K,V>, Serializable
```
A Map.Entry tied to a map underneath.
This can be used to enable a map entry to make changes on the underlying map, however this will probably mess up any iterators.
