ListMapView<K, V> class

A ListMapView lets you view a regular map as if it was a ListMap. At the moment this class is for FIC's internal use only, since a lot of its methods will throw UnsupportedError.

Methods

addAll(Map other) → void
Adds all key/value pairs of other to this map.
override
addEntries(Iterable<MapEntry> newEntries) → void
Adds all key/value pairs of newEntries to this map.
override
cast<RK, RV>() → ListMap<RK, RV>
Provides a view of this map as having RK keys and RV instances, if necessary.
override
clear() → void
Removes all entries from the map.
override
containsKey(covariant K? key) → bool
Whether this map contains the given key.
override
containsValue(covariant V? value) → bool
Whether this map contains the given value.
override
entry(K key) → MapEntry<K, V>
Return the key/value entry for the given key, or throws if key is not in the map.
override
entryAt(int index) → MapEntry<K, V>
Returns the indexth entry. The index must be non-negative and less than length. Index zero represents the first entry.
override
entryOrNull(K key) → MapEntry<K, V>?
Return the key/value entry for the given key, or null if key is not in the map.
override
entryOrNullValue(K key) → MapEntry<K, V?>
Return the key/value entry for the given key. If the key is not in the map, return MapEntry(key, null).
override
forEach(void f(K key, V value)) → void
Applies action to each key/value pair of the map.
override
get(covariant K key) → V?
The value for the given key, or null if key is not in the map.
override
getOrThrow(K key) → V
Returns the value if it exists, otherwise throws a StateError.
override
indexOfKey(K key, [int start = 0]) → int
The first index of key in this list.
override
keyAt(int index) → K
Returns the indexth key. The index must be non-negative and less than length. Index zero represents the first key.
override
map<K2, V2>(MapEntry<K2, V2> f(K key, V value)) → Map<K2, V2>
Returns a new map where all entries of this map are transformed by the given convert function.
override
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
putIfAbsent(K key, dynamic ifAbsent()) → V
Look up the value of key, or add a new entry if it isn't there.
override
remove(Object? key) → V
Removes key and its associated value, if present, from the map.
override
removeWhere(bool predicate(K key, V value)) → void
Removes all entries of this map that satisfy the given test.
override
shuffle([Random? random]) → void
Shuffles the keys of this map randomly.
override
sort([int compare(K a, K b)?]) → void
Sorts the keys of this map.
override
toString() → String
A string representation of this object.
inherited
update(K key, dynamic update(V value), {dynamic ifAbsent()?}) → V
Updates the value for the provided key.
override
updateAll(V? update(K key, V value)) → void
Updates all values.
override
valueAt(int index) → V
Returns the indexth value. The index must be non-negative and less than length. Index zero represents the first value.
override

Operators

operator ==(Object other) → bool
The equality operator.
inherited
operator [](covariant K key) → V?
The value for the given key, or null if key is not in the map.
override
operator []=(K key, V? value) → void
Replaces the value of a key that already exists in the map. However, if the key is not already present, this will throw an error.
