class Lense
[source: scala/collection/jcl/SortedMap.scala]
protected class Lense[F](f : (E) => F, g : (F) => E)
extends Lense[F] with Projection[K, F]
Method Summary
def compare (k0 : K, k1 : K) : Int
Comparison function that orders keys.
override def filterKeys (p : (K) => Boolean) : Projection[K, F]
non-strict filter based on keys only
override def lense [G](f0 : (F) => G, g0 : (G) => F) : Projection[K, G]
override def rangeImpl (from : Option[K], until : Option[K]) : Projection[K, F]
Creates a ranged projection of this collection. Any mutations in the ranged projection will update this collection and vice versa. Keys are garuanteed to be consistent between the collection and its projection.

Overrides
Lense.lense
override def rangeImpl(from : Option[K], until : Option[K]) : Projection[K, F]
Creates a ranged projection of this collection. Any mutations in the ranged projection will update this collection and vice versa. Keys are garuanteed to be consistent between the collection and its projection.
Parameters
from - The lower-bound (inclusive) of the ranged projection. None if there is no lower bound.
until - The upper-bound (exclusive) of the ranged projection. None if there is no upper bound.
