Method Summary | |
override def
|
+
[B1 >: B](kv : (A, B1)) : HashMap[A, B1]
Add a key/value pair to this map.
|
override def
|
+
[B1 >: B](elem1 : (A, B1), elem2 : (A, B1), elems : (A, B1)*) : HashMap[A, B1]
Adds two or more elements to this collection and returns
either the collection itself (if it is mutable), or a new collection
with the added elements.
|
def
|
-
(key : A) : HashMap[A, B]
Removes a key from this map, returning a new map
|
override def
|
empty : HashMap[A, B] |
def
|
get
(key : A) : Option[B]
Check if this map maps
key to a value and return the
value as an option if it exists, None if not. |
def
|
iterator
: Iterator[(A, B)]
An iterator yielding all key/value mappings of this map.
|
override def
|
size
: Int
Returns the size of this hash table.

override def
|
updated
[B1 >: B](key : A, value : B1) : HashMap[A, B1]
Add a key/value pair to this map.
