Map[A, B]Method Summary | |
def
|
-
(key : A) : Map[A, B]
Remove a key from this map
|
def
|
elements
: Iterator[(A, B)]
Creates a new iterator over all elements contained in this
object.
|
def

empty
[C] : Map[A, C]
This method returns a new map instance of the same class
mapping keys of the same type to values of type
C . |
def

get
(key : A) : Option[B]
Check if this map maps
key to a value and return the
value if it exists. |
def

size
: Int
Compute the number of key-to-value mappings.
|
def
|
update
[B1 >: B](key : A, value : B1) : Map[A, B1]
This method allows one to create a new map with an
additional mapping from
key
to value . If the map contains already a
