Class Description

A unique object used for retrieving items from the ReflectiveInjector.

Keys have:

  • a system-wide unique id.
  • a token.

Key is used internally by ReflectiveInjector because its system-wide unique id allows the injector to store created objects in a more efficient way.

Key should not be created directly. ReflectiveInjector creates keys automatically when resolving providers.


constructor(token: Object, id: number)


Static Members

get(token: Object) : ReflectiveKey

Retrieves a Key for a token.

numberOfKeys : number
