Method Summary
override def firstKey : A
Returns the first key of the collection.
override def from (from : A) : This
Creates a ranged projection of this collection with no upper-bound.
override def keySet : This
return as a projection the set of keys in this collection
override def lastKey : A
Returns the last key of the collection.
override def range (from : A, until : A) : This
Creates a ranged projection of this collection with both a lower-bound and an upper-bound.
abstract def rangeImpl (from : Option[A], until : Option[A]) : This
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 def subsetOf (that : Set[A]) : Boolean
Checks if this set is a subset of set that.
override def until (until : A) : This
Creates a ranged projection of this collection with no lower-bound.

return as a projection the set of keys in this collection
Overrides

Overrides
Sorted.firstKey
override def lastKey : A

abstract def rangeImpl(from : Option[A], until : Option[A]) : This
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
Sorted.rangeImpl
override def from(from : A) : This
Creates a ranged projection of this collection with no upper-bound.
Parameters
from - The lower-bound (inclusive) of the ranged projection.
Overrides
Sorted.from
override def until(until : A) : This
Creates a ranged projection of this collection with no lower-bound.
Parameters
until - The upper-bound (exclusive) of the ranged projection.
Overrides
Sorted.until
override def range(from : A, until : A) : This
Creates a ranged projection of this collection with both a lower-bound and an upper-bound.
Parameters
from - The upper-bound (exclusive) of the ranged projection.
until - ...
Returns
...
Overrides
Sorted.range
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
SetTemplate.subsetOf
