class ReflectiveKey {
static numberOfKeys: number
static get(token: Object): ReflectiveKey
constructor(token: Object, id: number)
displayName: string
token: Object
id: number
}
说明
Keys have:
- a system-wide unique
id. - a
token.
Key is used internally by ReflectiveInjectorbecause its system-wide unique id allows the injector to store created objects in a more efficient way.
Key should not be created directly. ReflectiveInjectorcreates keys automatically when resolving providers.
