object Map

object Map
extends java.lang.Object
with scala.ScalaObject

This class extends the Map interface of collections that unambiguously map keys to values (i.e. a key is mapped to at least one value).

This class defines the interface for functional map implementations relying on immutable data structures.

Concrete map implementations have to provide functionality for the abstract methods in scala.collection.Map as well as for factory, update, and -.
