类 FlexibleHashMap<K,V>

java.lang.Object

org.antlr.v4.runtime.misc.FlexibleHashMap<K,V>

所有已实现的接口:

Map<K,V>

直接已知子类:

PredictionContext.IdentityHashMap

public class FlexibleHashMap<K,V>
extends Object
implements Map<K,V>

A limited map (many unsupported operations) that lets me use varying hashCode/equals.
