trait Projection

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

trait Projection[K, E]: extends MutableIterableProjection[(K, E)] with Projection[K, E] with Map[K, E]

Direct Known Subclasses:: Map.Lense, Map.Filter, SortedMap.Projection

Method Summary
`override def`	map [B](f : ((K, E)) => B) : Projection[B] non-strict
`override def`	projection : Projection[K, E] returns a projection that can be used to call non-strict `filter`, `map`, and `flatMap` methods that build projections of the collection.
