class IdentityHashMap [K, E]
extends scala.collection.jcl.ConcreteMapWrapper[K, E]

A map that is backed by a Java identity hash map, which compares keys by their reference-based identity as opposed to using equals and hashCode. An identity hash map will often perform better than traditional hash map because it can utilize linear probing.
