  static get(token: Object): ReflectiveKey
  get numberOfKeys: number
  token: Object
  id: number
  get displayName: string
}

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.
