Class OrderedHashMap<K,V>

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>, SequencedMap<K,V>

public class OrderedHashMap<K,V>
extends LinkedHashMap<K,V>

I need the get-element-i functionality so I'm subclassing LinkedHashMap.
