Method Summary
`override def` | contains (key : K) : Boolean Is the given key mapped to a value by this map?
`override def` | elements : MutableIterator[(K, E)] Creates a new iterator over all elements contained in this object.
`override def` | get (key : K) : Option[E] Check if this map maps `key` to a value and return the value if it exists.
`override def` | put (key : K, elem : E) : Option[E]
`override def` | remove (key : K) : Option[E]
`override def` | size : Int Compute the number of key-to-value mappings.

Method Details

`override` `def` elements : MutableIterator[(K, E)]

  Creates a new iterator over all elements contained in this object.

Returns
  the new iterator

Overrides
  Map.elements

`override` `def` remove(key : K) : Option[E]

Overrides
  Map.remove

`override` `def` contains(key : K) : Boolean

  Is the given key mapped to a value by this map?

Parameters
  `key -` the key
Returns
  `true` iff there is a mapping for key in this map

`override` `def` put(key : K, elem : E) : Option[E]

Overrides
  Map.put

`override` `def` get(key : K) : Option[E]

  Check if this map maps `key` to a value and return the value if it exists.

Parameters
  `key -` the key of the mapping of interest
Returns
  the value of the mapping, if it exists

Overrides
  Map.get

`override` `def` size : Int

  Compute the number of key-to-value mappings.

Returns
  the number of mappings
