SetMultimap<K, V> class

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

Constructors

SetMultimap()
SetMultimap.fromIterable(Iterable iterable, { K key(dynamic element), V value(dynamic element) })
Constructs a new set-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. [...]
read-only, inherited
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.

values → Iterable<V>
The values of this.

Methods

asMap() → Map<K, Set<V>>
Returns a view of this multimap as a map.
override
removeAll(Object key) → Set<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, C 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.

Operators

operator [](Object key) → Set<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. [...]
