we now have two types of namespaces: - true namespace: angular.* - used for all global apis - virtual namespace: ng.*, ngMock.*, ... - used for all DI modules the virual namespaces have services under the second namespace level (e.g. ng.) and filters and directives prefixed with filter: and directive: respectively (e.g. ng.filter:orderBy, ng.directive:ngRepeat) this simplifies urls and makes them a lot shorter while still avoiding name collisions

|
|
* `NgModelController` provides API for the `ng-model` directive. The controller contains
|
|
* services for data-binding, validation, CSS update, value formatting and parsing. It
|
|
* specifically does not contain any logic which deals with DOM rendering or listening to
|
|
* DOM events. The `NgModelController` is meant to be extended by other directives where, the
|
|
* directive provides DOM manipulation and the `NgModelController` provides the data-binding.
|
|
*
|
|
* This example shows how to use `NgModelController` with a custom control to achieve
|
|
* data-binding. Notice how different directives (`contenteditable`, `ng-model`, and `required`)
|
|
* collaborate together to achieve the desired result.

* - providing validation behavior (i.e. required, number, email, url),
|
|
* - keeping state of the control (valid/invalid, dirty/pristine, validation errors),

|
* - setting related css class onto the element (`ng-valid`, `ng-invalid`, `ng-dirty`, `ng-pristine`),
