Node[B1 >: B](protected val override key : A, protected val override value : B1)
extends ListMap[A, B1]| Method Summary | |
override def
|
-
(k : A) : ListMap[A, B1]
Creates a new mapping without the given
key.
If the map does not contain a mapping for the given key, the
method returns the same map. |
override def
|
apply
(k : A) : B1
Retrieves the value which is associated with the given key. This
method throws an exception if there is no mapping from the given
key to a value.
|
override def
|
get
(k : A) : Option[B1]
Checks if this map maps
key to a value and return the
value if it exists. |
override def
|
isEmpty
: Boolean
Is this an empty map?
|
protected override def
|
next : ListMap[A, B1] |
override def
|
size
: Int
Returns the number of mappings in this map.
|
override def
|
updated
[B2 >: B1](k : A, v : B2) : ListMap[A, B2]
This method allows one to create a new map with an
additional mapping from
key
to value. If the map contains already a
mapping for key, it will be overridden by this
function. |
