class IdentityHashMap

[source: scala/collection/jcl/IdentityHashMap.scala]

class IdentityHashMap[K, E](val override underlying : IdentityHashMap)
extends MapWrapper[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.
