class KeySet
[source: scala/collection/jcl/SortedMap.scala]
protected class KeySet
extends KeySet with Projection[K]
Direct Known Subclasses:
SortedMapWrapper.KeySet
Method Summary
def compare (k0 : K, k1 : K) : Int
Comparison function that orders keys.
override def firstKey : K
Returns the first key of the collection.
override def lastKey : K
Returns the last key of the collection.
override def rangeImpl (from : Option[K], until : Option[K]) : Projection[K]
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.

def compare(k0 : K, k1 : K) : Int
Comparison function that orders keys.
override def firstKey : K
Returns the first key of the collection.
override def lastKey : K
Returns the last key of the collection.
override def rangeImpl(from : Option[K], until : Option[K]) : Projection[K]
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.
