[iterator]

• "[iterator]"(): MapIterator<[string, Inode]>

  Returns an iterable of entries in the map.

  Returns MapIterator<[string, Inode]>

clear

• clear(): void

  Returns void

delete

• delete(key: string): boolean

  Parameters

  • key: string

  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<[string, Inode]>

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

  Returns MapIterator<[string, Inode]>

forEach

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

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

  Parameters

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

  Returns void

get

• get(key: string): undefined | Inode

  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: string

  Returns undefined | Inode

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

has

• has(key: string): boolean

  Parameters

  • key: string

  Returns boolean

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

keys

• keys(): MapIterator<string>

  Returns an iterable of keys in the map

  Returns MapIterator<string>

set

• set(key: string, value: Inode): 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: string
  • value: Inode

  Returns this

values

• values(): MapIterator<Inode>

  Returns an iterable of values in the map

  Returns MapIterator<Inode>

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[]>
