[iterator]

• "[iterator]"(): MapIterator<[keyof defaultExtensions, BaseExtension]>

  Returns an iterable of entries in the map.

  Returns MapIterator<[keyof defaultExtensions, BaseExtension]>

clear

• clear(): void

  Returns void

delete

• delete(key: keyof defaultExtensions): boolean

  Parameters

  • key: keyof defaultExtensions

  Returns boolean

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

entries

• entries(): MapIterator<[keyof defaultExtensions, BaseExtension]>

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

  Returns MapIterator<[keyof defaultExtensions, BaseExtension]>

forEach

• forEach(
      callbackfn: (
          value: BaseExtension,
          key: keyof defaultExtensions,
          map: Map<keyof defaultExtensions, BaseExtension>,
      ) => void,
      thisArg?: any,
  ): void

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

  Parameters

  • callbackfn: (
        value: BaseExtension,
        key: keyof defaultExtensions,
        map: Map<keyof defaultExtensions, BaseExtension>,
    ) => void
  • OptionalthisArg: any

  Returns void

has

• has(key: keyof defaultExtensions): boolean

  Parameters

  • key: keyof defaultExtensions

  Returns boolean

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

keys

• keys(): MapIterator<keyof defaultExtensions>

  Returns an iterable of keys in the map

  Returns MapIterator<keyof defaultExtensions>

set

• set(key: keyof defaultExtensions, value: BaseExtension): 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: keyof defaultExtensions
  • value: BaseExtension

  Returns this

values

• values(): MapIterator<BaseExtension>

  Returns an iterable of values in the map

  Returns MapIterator<BaseExtension>

StaticgroupBy

• groupBy<K, T>(
      items: Iterable<T>,
      keySelector: (item: T, index: number) => K,
  ): Map<K, T[]>

  Groups members of an iterable according to the return value of the passed callback.

  Type Parameters

  • K
  • T

  Parameters

  • items: Iterable<T>

    An iterable.

  • keySelector: (item: T, index: number) => K

    A callback which will be invoked for each item in items.

  Returns Map<K, T[]>
