Class DynamicMap<K, V>

constructor

• new DynamicMap<K, V>(fnCreateValue: (key: K) => V): DynamicMap<K, V>

  Type Parameters

  • K
  • V

  Parameters

  • fnCreateValue: (key: K) => V

  Returns DynamicMap<K, V>

[toStringTag]

ReadonlyfnCreateValue

length

• get length(): number

  Returns number

size

• get size(): number

  Returns number

[iterator]

• "[iterator]"(): MapIterator<[K, V]>

  Returns MapIterator<[K, V]>

clear

• clear(): void

  Returns void

delete

• delete(key: K): boolean

  Parameters

  • key: K

  Returns boolean

entries

• entries(): MapIterator<[K, V]>

  Returns MapIterator<[K, V]>

forEach

• forEach(
      callbackfn: (value: V, key: K, map: Map<K, V>) => void,
      thisArg?: any,
  ): void

  Parameters

  • callbackfn: (value: V, key: K, map: Map<K, V>) => void
  • OptionalthisArg: any

  Returns void

get

• get(key: K): V

  Returns a specified element from the Map object.

  Parameters

  • key: K

  Returns V

  Returns the element associated with the specified key. If no element is associated with the specified key, the value is created.

  Note

  If the key does not exist in the dynamic map, the fnCreateValue callback will be invoked to create the key. The resulting value is then internally retained by the dynamic map.

  If the value that is associated to the provided key is an object, then you will get a reference to that object and any change made to that object will effectively modify it inside the Map.

has

• has(key: K): boolean

  Parameters

  • key: K

  Returns boolean

keys

• keys(): MapIterator<K>

  Returns MapIterator<K>

set

• set(key: K, value: V): this

  Parameters

  • key: K
  • value: V

  Returns this

values

• values(): MapIterator<V>

  Returns MapIterator<V>
