class
ImmutableMapAdaptor[A, B](protected val
imap : Map[A, B])
extends
Map[A, B]empty
has
to be redefined if the immutable map on which this mutable map is
originally based is not empty. empty
is supposed to
return the representation of an empty map.Method Summary | |
def
|
-=
(key : A) : Unit
Remove a key from this map, noop if key is not present.
|
override def
|
apply
(key : A) : B
Retrieve 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
|
clear
: Unit
Removes all mappings from the map. After this operation is
completed, the map is empty.
|
override def
|
contains
(key : A) : Boolean
Is the given key mapped to a value by this map?
|
def
|
elements
: Iterator[(A, B)]
Creates a new iterator over all elements contained in this
object.
|
def
|
get
(key : A) : Option[B]
Check if this map maps
key to a value and return the
value if it exists. |
override def
|
isDefinedAt
(key : A) : Boolean
Does this map contain a mapping from the given key to a value?
|
override def
|
isEmpty
: Boolean
Is this an empty map?
|
override def
|
keySet : Set[A] |
override def
|
keys
: Iterator[A]
Creates an iterator for all keys.
|
override def
|
retain
(p : (A, B) => Boolean) : Unit
This method retains only those mappings for which the predicate
p returns true . |
def
|
size
: Int
Compute the number of key-to-value mappings.
|
override def
|
toList
: List[(A, B)]
Create a fresh list with all the elements of this iterable object.
|
override def
|
toString
: String
Creates a string representation for this map.
|
override def
|
transform
(f : (A, B) => B) : Unit
This function transforms all the values of mappings contained
in this map with function
f . |
def
|
update
(key : A, value : B) : Unit
This method allows one to add a new mapping from
key
to value to the map. If the map already contains a
mapping for key , it will be overridden by this
function. |
override def
|
values
: Iterator[B]
Creates an iterator for a contained values.
