FlexibleHashMap

java.lang.Object
- org.graalvm.shadowed.org.antlr.v4.runtime.misc.FlexibleHashMap<K,V>

All Implemented Interfaces:

Map<K,V>
```
public class FlexibleHashMap<K,V>
extends Object
implements Map<K,V>
```
A limited map (many unsupported operations) that lets me use varying hashCode/equals.
