OrderedHashMap (ANTLR 4 Tool 4.13.1 API)

java.lang.Object
- java.util.AbstractMap<K,V>
- - java.util.HashMap<K,V>
  - - java.util.LinkedHashMap<K,V>
    - - org.antlr.v4.misc.OrderedHashMap<K,V>

All Implemented Interfaces:

Serializable, Cloneable, Map<K,V>
```
public class OrderedHashMap<K,V>
extends LinkedHashMap<K,V>
```
I need the get-element-i functionality so I'm subclassing LinkedHashMap.
