export class Key
export class Key
exported from angular2/core defined in angular2/src/core/di/key.ts (line 6)
A unique object used for retrieving items from the Injector
.
Keys have:
- a system-wide unique
id
. - a
token
.
Key
is used internally by Injector
because its system-wide unique id
allows the
injector to store created objects in a more efficient way.
Key
should not be created directly. Injector
creates keys automatically when resolving
providers.
