Type Summary
protected final type SortedSelf
Method Summary
protected def Range (from : Option[K], until : Option[K]) : Projection[K, E]
override abstract def compare (k0 : K, k1 : K) : Int
Comparison function that orders keys.
override def filterKeys (p : (K) => Boolean) : Projection[K, E]
non-strict filter based on keys only
override def firstKey : K
Returns the first key of the collection.
override def keySet : Projection[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 lense [F](f : (E) => F, g : (F) => E) : Projection[K, F]
override def projection : Projection[K, E]
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[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.

Type Details
protected final type SortedSelf
Method Details
override abstract def compare(k0 : K, k1 : K) : Int
Comparison function that orders keys.
override def firstKey : K
Returns the first key of the collection.
Overrides
SortedMap.firstKey
override def lastKey : K
Returns the last key of the collection.
Overrides
SortedMap.lastKey
override 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.
