scala.collection.SortedMap

class DefaultKeySet
[source: scala/collection/SortedMap.scala]
protected class DefaultKeySet
extends SortedSet[K]
Method Summary
def compare (k0 : K, k1 : K) : Int
Comparison function that orders keys.
def contains (key : K) : Boolean
Checks if this set contains element elem.
def elements : Iterator[K]
Creates a new iterator over all elements contained in this object.
override def rangeImpl (from : Option[K], until : Option[K]) : SortedSet[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 size : Int
Returns the number of elements in this set.

Method Details
def size : Int
Returns the number of elements in this set.
Returns
number of set elements.
def contains(key : K) : Boolean
Checks if this set contains element elem.
Parameters
elem - the element to check for membership.
Returns
true iff elem is contained in this set.
def elements : Iterator[K]
Creates a new iterator over all elements contained in this object.
Returns
the new iterator
def compare(k0 : K, k1 : K) : Int
Comparison function that orders keys.
override def rangeImpl(from : Option[K], until : Option[K]) : SortedSet[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.
Overrides
SortedSet.rangeImpl
