OpaqueToken

export class OpaqueToken

exported from angular2/core defined in angular2/src/core/di/opaque_token.ts (line 1)

Creates a token that can be used in a DI Provider.

Example (live demo)

var t = new OpaqueToken("value"); var injector = Injector.resolveAndCreate([ provide(t, {useValue: "providedValue"}) ]); expect(injector.get(t)).toEqual("bindingValue");

Using an OpaqueToken is preferable to using strings as tokens because of possible collisions caused by multiple providers using the same string as two different tokens.

Using an OpaqueToken is preferable to using an Object as tokens because it provides better error messages.
