Method Summary
def -= (key : A) : Unit
Remove a key from this map, noop if key is not present.
override def apply (key : A) : B
Retrieve the value which is associated with the given key. This method throws an exception if there is no mapping from the given key to a value.
override def clear : Unit
Removes all mappings from the map. After this operation is completed, the map is empty.
override def clone : Map[A, B]
Return a clone of this map.
override def contains (key : A) : Boolean
Is the given key mapped to a value by this map?
def elements : Iterator[(A, B)]
Creates a new iterator over all elements contained in this object.
def get (key : A) : Option[B]
Check if this map maps key to a value and return the value if it exists.
override def isDefinedAt (key : A) : Boolean
Does this map contain a mapping from the given key to a value?
override def isEmpty : Boolean
Is this an empty map?
override def keys : Iterator[A]
Creates an iterator for all keys.
def size : Int
Compute the number of key-to-value mappings.
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.
override def values : Iterator[B]
Creates an iterator for a contained values.

Method Details
def size : Int
Compute the number of key-to-value mappings.
Returns
the number of mappings
def get(key : A) : Option[B]
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
override def isEmpty : Boolean
Is this an empty map?
Returns
true iff the map is empty.
override def apply(key : A) : B
Retrieve the value which is associated with the given key. This method throws an exception if there is no mapping from the given key to a value.
Parameters
key - the key
Returns
the value associated with the given key.
override def contains(key : A) : 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 isDefinedAt(key : A) : Boolean
Does this map contain a mapping from the given key to a value?
Parameters
key - the key
Returns
true iff there is a mapping for key in this map
override def keys : Iterator[A]
Creates an iterator for all keys.
Returns
an iterator over all keys.
override def values : Iterator[B]
Creates an iterator for a contained values.
Returns
an iterator over all values.
def elements : Iterator[(A, B)]
Creates a new iterator over all elements contained in this object.
Returns
the new iterator
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.
Parameters
key - The key to update
value - The new value
Overrides
Map.update
def -=(key : A) : Unit
Remove a key from this map, noop if key is not present.
Parameters
key - the key to be removed
Overrides
Map.-=
override def clear : Unit
Removes all mappings from the map. After this operation is completed, the map is empty.
Overrides
Map.clear
override def clone : Map[A, B]
Return a clone of this map.
Returns
a map with the same elements.
Overrides
Map.clone
