trait SortedSet

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

trait SortedSet[A]
extends SortedSet[A] with Set[A] with Sorted[A, A]
Analogous to a Java sorted set.

Direct Known Subclasses:
SortedSet.Projection, SortedSetWrapper

Type Summary
protected final type SortedSelf
Method Summary
abstract def compare (a0 : A, a1 : A) : Int
Comparison function that orders keys.
override def firstKey : A
Returns the first key of the collection.
override def hasAll (that : Iterable[A]) : Boolean
Type-safe version of containsAll. * * @author Sean McDirmid
override def keySet : SortedSet[A]
return as a projection the set of keys in this collection
override def lastKey : A
Returns the last key of the collection.
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.
override def rangeImpl (from : Option[A], until : Option[A]) : SortedSet[A]
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.
override def subsetOf (that : Set[A]) : Boolean
Checks if this set is a subset of set that.

Type Details

Method Details
override def keySet : SortedSet[A]
return as a projection the set of keys in this collection
Overrides
SortedSet.keySet, Sorted.keySet

abstract def compare(a0 : A, a1 : A) : Int
Comparison function that orders keys.

override def firstKey : A
Returns the first key of the collection.
Overrides
SortedSet.firstKey

override def subsetOf(that : Set[A]) : Boolean
Checks if this set is a subset of set that.
Parameters
that - another set.
Returns
true iff the other set is a superset of this set. todo: rename to isSubsetOf
Overrides
SortedSet.subsetOf, Set.subsetOf

override def hasAll(that : Iterable[A]) : Boolean
Type-safe version of containsAll. * * @author Sean McDirmid

override def lastKey : A
Returns the last key of the collection.
Overrides
SortedSet.lastKey

override def rangeImpl(from : Option[A], until : Option[A]) : SortedSet[A]
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, Sorted.rangeImpl

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.
Overrides
Set.projection
