extends
Iterable[A]Method Summary | |
abstract def
|
compare
(k0 : K, k1 : K) : Int
Comparison function that orders keys.
|
abstract def
|
firstKey
: K
Returns the first key of the collection.
|
def
|
from
(from : K) : Ranged[K, A]
Creates a ranged projection of this collection with no upper-bound.
|
abstract def
|
lastKey
: K
Returns the last key of the collection.
|
def
|
range
(from : K, until : K) : Ranged[K, A]
Creates a ranged projection of this collection with both a lower-bound
and an upper-bound.
|
abstract def
|
rangeImpl
(from : Option[K], until : Option[K]) : Ranged[K, A]
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.

def
|
until
(until : K) : Ranged[K, A]
Creates a ranged projection of this collection with no lower-bound.
