trait SortedMap[K, +E]
extends Map[K, E] with Sorted[K, (K, E)]
A map whose keys are sorted.

Direct Known Subclasses:
SortedMap, SortedMap
Method Summary
override def firstKey : K
Returns the first key of the collection.
override def from (from : K) : SortedMap[K, E]
Creates a ranged projection of this collection with no upper-bound.
override def keySet : SortedSet[K]
return as a projection the set of keys in this collection
override def lastKey : K
Returns the last key of the collection.
override def range (from : K, until : K) : SortedMap[K, E]
Creates a ranged projection of this collection with both a lower-bound and an upper-bound.
override abstract def rangeImpl (from : Option[K], until : Option[K]) : SortedMap[K, E]
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 until (until : K) : SortedMap[K, E]
Creates a ranged projection of this collection with no lower-bound.

Method Details
override def firstKey : K
Returns the first key of the collection.
override def lastKey : K
Returns the last key of the collection.
override abstract def rangeImpl(from : Option[K], until : Option[K]) : SortedMap[K, E]
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
Sorted.rangeImpl
override def from(from : K) : SortedMap[K, E]
