The singleton service that represents the top level router was called
`$router` but this is confusing since there are actually lots of routers,
which depend upon where you are in the DOM. This is similar to the situation
with scopes.
This commit clarifies this singleton by renaming it to `$rootRouter`.
BREAKING CHANGE:
The `$router` injectable service has been renamed to `$rootRouter`
BREAKING CHANGE:
Previously, components that would implement lifecycle interfaces would include methods
like "onChanges" or "afterViewInit." Given that components were at risk of using such
names without realizing that Angular would call the methods at different points of
the component lifecycle. This change adds an "ng" prefix to all lifecycle hook methods,
far reducing the risk of an accidental name collision.
To fix, just rename these methods:
* onInit
* onDestroy
* doCheck
* onChanges
* afterContentInit
* afterContentChecked
* afterViewInit
* afterViewChecked
* _Router Hooks_
* onActivate
* onReuse
* onDeactivate
* canReuse
* canDeactivate
To:
* ngOnInit,
* ngOnDestroy,
* ngDoCheck,
* ngOnChanges,
* ngAfterContentInit,
* ngAfterContentChecked,
* ngAfterViewInit,
* ngAfterViewChecked
* _Router Hooks_
* routerOnActivate
* routerOnReuse
* routerOnDeactivate
* routerCanReuse
* routerCanDeactivate
The names of lifecycle interfaces and enums have not changed, though interfaces
have been updated to reflect the new method names.
Closes#5036
BREAKING CHANGE:
Previously, route configuration took a controller constructor function as the value of
`component` in a route definition:
```
$route.config([
{ route: '/', component: MyController }
])
```
Based on the name of the controller, we used to use a componentMapper service to
determine what template to pair with each controller, how to bind the instance to
the $scope.
To make the 1.x router more semantically alligned with Angular 2, we now route to a directive.
Thus a route configuration takes a normalized directive name:
```
$route.config([
{ route: '/', component: 'myDirective' }
])
```
BREAKING CHANGE:
In order to avoid name collisions, lifecycle hooks are now prefixed with `$`. Before:
```
MyController.prototype.onActivate = ...
```
After:
```
MyController.prototype.$onActivate = ...
```
Same for `$canActivate` (which now lives on the directive factory function),
`$canDeactivate`, `$canReuse`, and `$onDeactivate` hooks.
