elements
: Iterator[(A, B)]
Creates a new iterator over all elements contained in this
object.

get
(key : A) : Option[B]
Check if this map maps
key to a value and return the
value if it exists. |
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. |
