OpenHashMap[Key, Value](initialSize : Int)
extends
Map[Key, Value]Additional Constructor Summary | |
def
|
this : OpenHashMap[Key, Value] |
Method Summary | |
def
|
-=
(key : Key) : Unit
Remove a key from this map, noop if key is not present.
|
override def
|
clone
: OpenHashMap[Key, Value]
Return a clone of this map.
|
def
|
elements
: Iterator[(Key, Value)]
An iterator over the elements of this map. Use of this iterator follows the same
contract for concurrent modification as the foreach method.
|
override def
|
foreach
(f : ((Key, Value)) => Unit) : Unit
Loop over the key, value mappings of this map.
The behaviour of modifying the map during an iteration is as follows:
|
def
|
get
(key : Key) : Option[Value]
Check if this map maps
key to a value and return the
value if it exists. |
protected def
|
hashOf (key : Key) : Int |
override def
|
retain
(f : (Key, Value) => 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
|
stringPrefix
: java.lang.String
Defines the prefix of this object's
toString representation. |
override def
|
transform
(f : (Key, Value) => Value) : Unit
This function transforms all the values of mappings contained
in this map with function
f . |
def
|
update
(key : Key, value : Value) : 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. |
