- Changes the `alreadyChecked` flag of AbstractChangeDetector to a new `state` flag.
- Changes all checks of alreadyChecked to check that the state is NeverChecked.
- Set state to Errored if an error is thrown during detection.
- Skip change detection for a detector and its children when the state is Errored.
- Add a test to validate this fixes issue #4323.
Closes#4953
Match [ViewResolver][]'s semantics for reading template and style values
from `@Component` and `@View` annotations.
We now warn if template and/or style values appear on an `@Component`
annotation and a `@View` annotation is present.

Previously, importing a library twice using different prefixes could
cause the template compiler step to incorrect omit `Directive`
dependencies provided by that library.
Previously, we parsed dependencies out of a the stringified value of
`directives`, which is brittle and error-prone.
Move this parsing into `DirectiveProcessor` where we have the full Dart
ast to help.
Previously, `DeferredRewriter` checked for the existence of
`.ng_deps.dart` files to determine which deferred libraries it needed to
rewrite, requiring that those assets exist at the time it was run.
Update to check for `.ng_meta.json` files instead, which exist after the
`DirectiveProcessor` phase. This allows the `DeferredRewriter` (which
only processes *.dart files) to run in
parallel with `TemplateComplier` (which only processes *.ng_meta.json
files) and `StylesheetCompiler` (which only processes *.css files).
Have DeferredRewriter to check existence of .ng_meta.json assets rather than .ng_deps.dart assets
Update `DirectiveProcessor` and `TemplateCompiler` to generate the
getters, setters, and methods currently generated in `BindGenerator`.
Update `DirectiveMetadataLinker` to output `.ng_meta.json` files instead
of `.ng_deps.dart` files, avoiding full codegen until the last phase.
This allows us to dedupe codegen logic and remove an additional phase
from the transformer.
The directory contains code authored in a style that makes it transpilable to dart. As such, these are not idiomatic examples of Angular 2 usage.
The main purpose of this directory is to enable experimentation with Angular within the angular/angular repository.

Now that we can specify `directives` in either `@View` or `@Component`,
we will try to parse from both.
Previously, we would trash any `directives` parsed in the first
annotation upon encountering the second annotation. This ensures that we
maintain that list of `directives` regardless of annotation ordering.
Handle the situation where a `.dart` file generates a `.ng_meta.json`
file but does not register any reflective information.
An example of this would be a file that defines a const list that looks
like a directive alias. The transformer keeps track of this, and creates
a `.ng_meta.json` file but never creates a `.ng_deps.dart` file, which
can result in other files being linked to it and it not defining an
`initReflector` method.
`DeferredRewriter` depends on the presence of `.ng_deps.dart` files,
which do not yet exist in the phase where it was previously run.
Update the transformer phases to fix this and add an integration test to
prevent regression.
Link `NgDeps` & `NgMeta` data in the same phase to avoid unnecessary asset
creation & reading.
Remove `NgMeta#exports` and instead use `NgDeps#exports` to link `NgMeta` files
in `ng_meta_linker.dart`.
Previously, annotations which were const objects (as opposed to const
instance creation expressions) were incorrectly output as instance
creation expressions.
Before:
```
const override() // A const instance creation expression
```
After
```
override // A const instance
```
Closes#4481
BREAKING CHANGE:
- Removes `ChangeDetection`, use a binding for `ChangeDetectorGenConfig` instead
to configure change detection.
- `RenderElementRef.renderBoundElementIndex` was renamed to `RenderElementRef.boundElementIndex`.
- Removes `ViewLoader`, use `XHRImpl` instead.
Closes#3605
BREAKING CHANGE:
- we don't mark an element as bound any more if it only contains text bindings
E.g. <div>{{hello}}</div>
This changes the indices when using `DebugElement.componentViewChildren` / `DebugElement.children`.
- `@Directive.compileChildren` was removed,
`ng-non-bindable` is now builtin and not a directive any more
- angular no more adds the `ng-binding` class to elements with bindings
- directives are now ordered as they are listed in the View.directives regarding change detection.
Previously they had an undefined order.
- the `Renderer` interface has new methods `createProtoView` and `registerComponentTemplate`. See `DomRenderer` for default implementations.
- reprojection with `ng-content` is now all or nothing per `ng-content` element
- angular2 transformer can't be used in tests that modify directive metadata.
Use `angular2/src/transform/inliner_for_test` transformer instead.
