It is possible for a class defined first to be referencing a class defined later,
and as a result at the time of the definition it is not possible to access the later's
class reference. This allows to refer to the later defined class through
a closure.Closes #1891
BREAKING CHANGE:
`AppViewManager.createInPlaceHostView` is replaced by
`AppViewManager.createRootHostView` (for bootstrap) and
`AppViewManager.createFreeHostView` (for imperative components).
The later creates new host elements that are not attached anywhere.
To attach them, use `DomRenderer.getHostElement(hostviewRef)`
to get the host element.
Closes#1920
Also consolidates metadata handling in `ElementInjector`
BREAKING CHANGE:
- renames `DirectiveMetadataReader` into `DirectiveResolver`
and removes `src/core/compiler/directive_metadata`.
Fixes#1712Fixes#1713
BREAKING CHANGE:
VmTurnZone has been renamed to NgZone.
- The public API has not chnanged,
- The "outer" zone is now named "mount" zone (private to NgZone).
Before this PR there were only 2 zones: root zone = outer zone > inner
zone.
This PR creates the outer zone as a fork of the root zone: root > outer
> inner.
By doing this it is possible to detected microtasks scheduling in the
outer zone and run the change detection less often (no more than one
time per VM turn).
The PR also introduce a Promise monkey patch for the JS implementation.
It makes Promises aware of microtasks and again allow running the change
detection only once per turn.
The goal is to make implementing a renderer straight forward.
BREAKING_CHANGE:
- Renderer interface was redone / simplified.
- `DirectDomRenderer` was replaced by `DomRenderer`.
- `DirectDomRenderer.setImperativeComponentRootNodes` is replaced
by the following 2 steps:
1. `ViewManager.getComponentView(elementRef) -> ViewRef`
2. `DomRenderer.setComponentViewRootNodes(viewRef, rootNodes)`
- all `@View` annotations need to have a template, but the template
may be empty. Previously views that had a `renderer` property did
not have to have a `template`.
- `dynamicComponentLoader.loadIntoNewLocation` does no more allow
to pass an element, but requires a css selector.
Special syntax: `:document` can be used as prefix to search globally
on the document instead of in the provided parent view.
Part of #1675
In 'angular2/di' the symbol:
- Inject is a decorator
- InjectAnnotation is an annotation
Internally one an get a hold of annotations without *Annotations appened
(to make ts2dart work without workarounds) by importing from
'angular2/src/di/annotations_impl' instead of 'angular2/di'. This is
needed only for users that transpile through TS and through ts2dart.
This removes .es6 files which are pure duplicates of a
.ts file in the same folder.
Next we need to remove .js files as well, and remove karma preprocessors for dart.
BREAKING CHANGE:
Previously, `Directive` was the abstract base class of several directives.
Now, `Directive` is the former `Decorator`, and `Component` inherits from it.
BREAKING_CHANGE:
- The special type of `Viewport` directives is removed
in favor of a more general `Decorator` directive
- `ViewContainerRef` now no more has a default `ProtoViewRef`
but requires an explicit one when creating views.
Closes#1536
BREAKING CHANGES:
- `NgElement` merged into `ElementRef`
- `Compiler.compile…` returns `ProtoViewRef`
- `ViewContainer` uses `ProtoViewRef`s and `ViewRef`s.
- `ViewRef`/`ProtoViewRef` in renderer were renamed to
`RenderViewRef`/`RenderProtoViewRef`.

AppViewManager is the single entry point to changing the view hierarchy.
It is split between the manager itself which does coordination and
helper methods, so both are easily testable in isolation.
Also, ViewContainer is now only a pure reference to a bound element
with the previous functionality but does not contain the list of views
any more.
Part of #1477
Major changes:
- `compiler.compileRoot(el, type)`
-> `compiler.compileInHost(type) + viewHydrator.hydrateHostViewInPlace(el, view)`
- move all `hydrate`/`dehydrate` methods out of `View` and `ViewContainer` into
a standalone class `view_hydrator` as private methods and provide new public
methods dedicated to the individual use cases.
Note: This PR does not change the current functionality, only moves it
into different places.
See design discussion in #1351, in preparation for imperative views.
Add two factory static functions to Injector: resolveAndCreate and
fromResolvedBindings.
We want to avoid resolution and flattening every time we create a new
injector. This commit allows the user to cache resolved bindings and
reuse them.
Queries allow a directive to inject a live list of directives of a given
type from its LightDom. The injected list is Iterable (in JS and Dart).
It will be Observable when Observables are support in JS, for now it
maintains a simple list of onChange callbacks API.
To support queries, element injectors now maintain a list of
child injectors in the correct DOM order (dynamically updated by
viewports).
For performance reasons we allow only 3 active queries in an injector
subtree. The feature adds no overhead to the application when not
used. Queries walk the injector tree only during dynamic view
addition/removal as triggered by viewport directives.
Syncs changes between viewContainer on the render and logic sides.
Closes#792
Introduces angular2/src/core/compiler/ViewFactory which
extracts ProtoView.instantiate and replaces ViewPool.
Note: This is a work in progress commit to unblock other commits.
There will be follow ups to add unit tests, remove TODOs, …
Needed to change Renderer.mergeChildComponentProtoViews to not create
new ProtoViews to be able to deal with cyclic references.
This commit is part of using the new render layer in Angular.
