Class UnmodifiableIdentityHashMap<K,V>

java.lang.Object

java.util.AbstractMap<K,V>

java.util.IdentityHashMap<K,V>

org.checkerframework.dataflow.util.UnmodifiableIdentityHashMap<K,V>

All Implemented Interfaces:

Serializable, Cloneable, Map<K,V>

public class UnmodifiableIdentityHashMap<K,V>
extends IdentityHashMap<K,V>

A wrapper around an IdentityHashMap that makes it unmodifiable. All mutating operations throw UnsupportedOperationException, and all other operations delegate to the underlying map.

This class extends IdentityHashMap only so it is assignable to variables / fields of static type IdentityHashMap. All valid operations are delegated to the wrapped map, and any inherited state from the superclass is unused.
