Class CMap<K, V>

constructor

• new CMap<K, V>(arr?: [K, V][]): CMap<K, V>

  Type Parameters

  • K
  • V

  Parameters

  • Optionalarr: [K, V][]

  Returns CMap<K, V>

[toStringTag]

size

[iterator]

• "[iterator]"(): IterableIterator<[K, V]>

  Returns IterableIterator<[K, V]>

clear

• clear(): void

  Returns void

delete

• delete(key: K): boolean

  Parameters

  • key: K

  Returns boolean

  true if an element in the Map existed and has been removed, or false if the element does not exist.

deleteSelected

• deleteSelected(selector: (value: V, key: K) => boolean): void

  Delete selected elements from the storage

  Parameters

  • selector: (value: V, key: K) => boolean

  Returns void

entries

• entries(): IterableIterator<[K, V]>

  Returns an iterable of key, value pairs for every entry in the map.

  Returns IterableIterator<[K, V]>

forEach

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

  Executes a provided function once per each key/value pair in the Map, in insertion order.

  Parameters

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

  Returns void

get

• get(key: K): undefined | V

  Returns a specified element from the Map object. 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.

  Parameters

  • key: K

  Returns undefined | V

  Returns the element associated with the specified key. If no element is associated with the specified key, undefined is returned.

has

• has(key: K): boolean

  Parameters

  • key: K

  Returns boolean

  boolean indicating whether an element with the specified key exists or not.

keys

• keys(): IterableIterator<K>

  Returns an iterable of keys in the map

  Returns IterableIterator<K>

map

• map<T>(mapper: (value: V, key: K) => T): T[]

  Return a array based on each element in storage

  Type Parameters

  • T

  Parameters

  • mapper: (value: V, key: K) => T

    mapping function

  Returns T[]

merge

• merge(map: CMap<K, V>, skipOverwrite?: boolean): this

  Merge another core-map in the existing, duplicated keys in the executing map will be overwritten

  Parameters

  • map: CMap<K, V>
  • OptionalskipOverwrite: boolean

  Returns this

set

• set(key: K, value: V): this

  Adds a new element with a specified key and value to the Map. If an element with the same key already exists, the element will be updated.

  Parameters

  • key: K
  • value: V

  Returns this

toKeyArray

• toKeyArray(): K[]

  Return an array with the keys only

  Returns K[]

toValueArray

• toValueArray(): V[]

  Return an array with the values only

  Returns V[]

values

• values(): IterableIterator<V>

  Returns an iterable of values in the map

  Returns IterableIterator<V>
