[source: scala/collection/jcl/Ranged.scala]
trait Ranged[K, A]
extends Ranged[K, A] with MutableIterable[A]
Any collection (including maps) whose keys (or elements) are ordered.

Buffer, Sorted
Type Summary
protected abstract type SortedSelf <: Ranged[K, A]
Method Summary
abstract def compare (k0 : K, k1 : K) : Int
Comparison function that orders keys.
override final def from (from : K) : SortedSelf
Creates a ranged projection of this collection with no upper-bound. * @param from The lower-bound (inclusive) of the ranged projection.
override final def range (from : K, until : K) : SortedSelf
Creates a ranged projection of this collection with both a lower-bound and an upper-bound. * @param from The upper-bound (exclusive) of the ranged projection.
abstract def rangeImpl (from : Option[K], until : Option[K]) : SortedSelf
Creates a ranged projection of this collection. Any mutations in the ranged projection will update this collection and vice versa. Note: keys are not garuanteed to be consistent between this collection and the projection. This is the case for buffers where indexing is relative to the projection.
override final def until (until : K) : SortedSelf
Creates a ranged projection of this collection with no lower-bound. * @param until The upper-bound (exclusive) of the ranged projection.

Type Details
protected abstract type SortedSelf <: Ranged[K, A]
Method Details
abstract def compare(k0 : K, k1 : K) : Int
Comparison function that orders keys.
Overrides
Ranged.compare
abstract def rangeImpl(from : Option[K], until : Option[K]) : SortedSelf
Creates a ranged projection of this collection. Any mutations in the ranged projection will update this collection and vice versa. Note: keys are not garuanteed to be consistent between this collection and the projection. This is the case for buffers where indexing is relative to the 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
Ranged.rangeImpl
override final def from(from : K) : SortedSelf
Creates a ranged projection of this collection with no upper-bound. * @param from The lower-bound (inclusive) of the ranged projection.
Overrides
Ranged.from
override final def until(until : K) : SortedSelf
Creates a ranged projection of this collection with no lower-bound. * @param until The upper-bound (exclusive) of the ranged projection.
Overrides
Ranged.until
override final def range(from : K, until : K) : SortedSelf
Creates a ranged projection of this collection with both a lower-bound and an upper-bound. * @param from The upper-bound (exclusive) of the ranged projection.
Overrides
