Class LinkedIdentityHashMap<K,V>

java.lang.Object

com.google.javascript.jscomp.base.LinkedIdentityHashMap<K,V>

All Implemented Interfaces:

Serializable

public final class LinkedIdentityHashMap<K,V>
extends Object
implements Serializable

A deterministic drop-in replacement for IdentityHashMap.

This class is actually "map-like" in that it doesn't fully implement the

invalid reference

Map

interface. Only the methods needed to eliminate IdentityHashMap were defined. The entire interface could be satisfied in the future if necessary.
