| Def Summary | |
def
++=
(it: scala.Iterator[scala.Tuple2[A, B]])
: scala.Unit
This method adds all the mappings provided by an iterator of parameter map to the map.
|
|
def
++=
(map: scala.Iterable[scala.Tuple2[A, B]])
: scala.Unit
This method adds all the mappings provided by an iterator of parameter map to the map.
|
|
def
+=
(key: A)
: Map.this.MapTo
This method defines syntactic sugar for adding or modifying mappings. It is typically used in the following way:
map += key -> value;
|
|
def
--=
(it: scala.Iterator[A])
: scala.Unit
This method removes all the mappings for keys provided by an iterator over the elements of the keys object.
|
|
def
--=
(keys: scala.Iterable[A])
: scala.Unit
This method removes all the mappings for keys provided by an iterator over the elements of the keys object.
|
|
abstract
|
def
-=
(key: A)
: scala.Unit
This method removes a mapping from the given key.
If the map does not contain a mapping for the given key, the
method does nothing.
|
def
<<
(cmd: scala.collection.mutable.Message[scala.Tuple2[A, B]])
: scala.Unit
Send a message to this scriptable object. |
|
def
clear
: scala.Unit
Removes all mappings from the map. After this operation is completed, the map is empty. |
|
override
|
def
clone
: scala.collection.mutable.Map[A, B]
Return a clone of this map. |
def
excl
(keys: A*)
: scala.Unit
This method will remove all the mappings for the given sequence of keys from the map. |
|
def
filter
(p: (scala.Tuple2[A, B]) => scala.Boolean)
: scala.Unit
This method removes all the mappings for which the predicate p returns false.
|
|
override
|
def
hashCode
: scala.Int
The hashCode method always yields an error, since it is not safe to use mutable maps as keys in hash tables. |
def
incl
(mappings: scala.Tuple2[A,B]*)
: scala.Unit
incl can be used to add many mappings at the same time
to the map. The method assumes that a mapping is represented
by a Pair object who's first component denotes the
key, and who's second component refers to the value.
|
|
def
map
(f: (scala.Tuple2[A, B]) => B)
: scala.Unit
This function transforms all the values of mappings contained in this map with function f.
|
|
def
mappingToString
(p: scala.Tuple2[A, B])
: java.lang.String
This method controls how a mapping is represented in the string representation provided by method toString.
|
|
override
|
def
toString
: java.lang.String
Returns a string representation of this map which shows all the mappings. |
abstract
|
def
update
(key: A, value: B)
: scala.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.
