ListMultimap<K, V> class

A multimap implementation that uses Lists to store the values associated with each key.

Constructors

ListMultimap()
ListMultimap.fromIterable(Iterable iterable, {K key(dynamic element), V value(dynamic element)})
Constructs a new list-backed multimap. For each element e of iterable, adds an association from key to value. key and value each default to the identity function.

Properties

hashCode int
The hash code for this object. [...]

isEmpty bool
Returns true if there is no key in the multimap.
read-only, inherited
isNotEmpty bool
Returns true if there is at least one key in the multimap.
read-only, inherited
keys Iterable<K>
The keys of this.
read-only, inherited
length int
The number of keys in the multimap.
read-only, inherited
runtimeType Type
A representation of the runtime type of the object.
read-only, inherited
values Iterable<V>
The values of this.

Methods

asMap() Map<K, List<V>>
Returns a view of this multimap as a map.
override
removeAll(Object key) List<V>
Removes the association for the given key. Returns the collection of removed values, or an empty iterable if key was unmapped.
add(K key, V value) → void
Adds an association from the given key to the given value.
inherited
addAll(Multimap<K, V> other) → void
Adds all associations of other to this multimap. [...]
inherited
addValues(K key, Iterable<V> values) → void
Adds an association from the given key to each of the given values.
inherited
clear() → void
Removes all data from the multimap.
inherited
contains(Object key, Object value) bool
Returns whether this multimap contains the given association between key and value.
inherited
containsKey(Object key) bool
Returns whether this multimap contains the given key.
inherited
containsValue(Object value) bool
Returns whether this multimap contains the given value.
inherited
forEach(void f(K key, V value)) → void
Applies f to each {key, value} pair of the multimap. [...]
inherited
forEachKey(void f(K key, List<V> value)) → void
Applies f to each {key, Iterable<value>} pair of the multimap. [...]
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed. [...]
inherited
remove(Object key, V value) bool
Removes the association between the given key and value. Returns true if the association existed, false otherwise.
inherited
toString() String
Returns a string representation of this object.
inherited

Operators

operator [](Object key) List<V>
Returns the values for the given key. An empty iterable is returned if key is not mapped. The returned collection is a view on the multimap. Updates to the collection modify the multimap and likewise, modifications to the multimap are reflected in the returned collection.
operator ==(dynamic other) bool
The equality operator. [...]
