class IdentityHashMap

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

  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.
