LinkedLruHashMap<K, V> class

A linked hash-table based implementation of LruMap.

Implemented types

• LruMap<K, V>

Constructors

LinkedLruHashMap({int? maximumSize})

Create a new LinkedLruHashMap with a maximumSize.

factory

Properties

entries → Iterable<MapEntry<K, V>>

The map entries of this.

no setter, override

hashCode → int

The hash code for this object.

no setter, inherited

isEmpty → bool

Whether there is no key/value pair in the map.

no setter, override

isNotEmpty → bool

Whether there is at least one key/value pair in the map.

no setter, override

keys → Iterable<K>

The keys of this - in order of MRU to LRU.

no setter, override

length → int

The number of key/value pairs in the map.

no setter, override

maximumSize ↔ int

Maximum size of the Map. If length exceeds this value at any time, n entries accessed the earliest are removed, where n is length - maximumSize.

getter/setter pair, override

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

values → Iterable<V>

The values of this - in order of MRU to LRU.

no setter, override

Methods

addAll(Map<K, V> other) → void

Adds all key-value pairs of other to this map.

override

addEntries(Iterable<MapEntry<K, V>> entries) → void

Adds all key/value pairs of newEntries to this map.

override

cast<K2, V2>() → LinkedLruHashMap<K2, V2>

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(Object? key) → bool

Whether this map contains the given key.

override

containsValue(Object? value) → bool

Whether this map contains the given value.

override

forEach(void action(K key, V value)) → void

Applies action to each key-value pair of the map in order of MRU to LRU.

override

map<K2, V2>(Object transform(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, V ifAbsent()) → V

Look up the value associated with key, or add a new value if it isn't there. The pair is promoted to the MRU position.

override

remove(Object? key) → V?

Removes key and its associated value, if present, from the map.

override

removeWhere(bool test(K key, V value)) → void

Removes all entries of this map that satisfy the given test.

override

toString() → String

A string representation of this object.

override

update(K key, V update(V value), {V ifAbsent()?}) → V

Updates the value for the provided key.

override

updateAll(V update(K key, V value)) → void

Updates all values.

override

Operators

operator ==(Object other) → bool

The equality operator.

inherited

operator [](Object? key) → V?

Get the value for a key in the Map. The key will be promoted to the 'Most Recently Used' position.

override

operator []=(K key, V value) → void

If key already exists, promotes it to the MRU position & assigns value.
