trait Projection
[source: scala/RandomAccessSeq.scala]
trait Projection[+A]
extends Projection[A] with RandomAccessSeq[A]
Direct Known Subclasses:
RandomAccessSeq.Projection.MapProjection, RandomAccessSeq.MutableProjection, Range, Buffer.Projection0
Method Summary
override def append [B >: A](that : => Iterable[B]) : Projection[B]
The projection resulting from the concatenation of this projection with the rest projection.
override def force : RandomAccessSeq[A]
convert to a copied strict collection
override def map [B](f : (A) => B) : Projection[B]
non-strict
override def projection : Projection[A]
returns a projection that can be used to call non-strict filter, map, and flatMap methods that build projections of the collection.
