* Dependency injection tokens that this component publishes _itself_ to its

* children in its view via the application injector.
|

*
|
||||
* ## Examples
|
||||
*
|
||||
* Imagine you have parent component that implements the [RpcService]
|
||||
* interface. It can pose as [RpcService] to its children. Child components
|
||||
* do not need to know about this fact. They only need to declare their
|
||||
* dependency on [RpcService] without knowing exactly how it is provided.
|
||||
*
|
||||
* ```
|
||||
* @Component({
|
||||
* selector: 'parent',
|
||||
* publishAs: [RpcService]
|
||||
* })
|
||||
* @View({
|
||||
* template: '<child></child>',
|
||||
* directives: [Child]
|
||||
* })
|
||||
* class Parent implements RpcService {
|
||||
* }
|
||||
*
|
||||
* @Component({
|
||||
* selector: 'child'
|
||||
* })
|
||||
* class Child {
|
||||
* // Just asks for RpcService; doesn't know that it's Parent.
|
||||
* constructor(RpcService rpc);
|
||||
* }

* ```
