A dependency injection container used for resolving dependencies.
An `Injector` is a replacement for a `new` operator, which can automatically resolve the constructor dependencies.
In typical use, application code asks for the dependencies in the constructor and they are resolved by the
`Injector`.
## Example:
Suppose that we want to inject an `Engine` into class `Car`, we would define it like this:
```javascript
class Engine {
}
class Car {
constructor(@Inject(Engine) engine) {
}
constructor(@Inject(Engine) engine) {
}
}
```
Next we need to write the code that creates and instantiates the `Injector`. We then ask for the `root` object,
`Car`, so that the `Injector` can recursively build all of that object's dependencies.
```javascript
main() {
var injector = Injector.resolveAndCreate([Car, Engine]);
// Get a reference to the `root` object, which will recursively instantiate the tree.
var car = injector.get(Car);
}
```
Notice that we don't use the `new` operator because we explicitly want to have the `Injector` resolve all of the
object's dependencies automatically.

recommended way to construct injectors in performance-sensitive parts.

Turns a list of binding definitions into an internal resolved list of resolved bindings.
A resolution is a process of flattening multiple nested lists and converting individual bindings into a
list of <a href="angular2/di/ResolvedBinding-class"><code>ResolvedBinding</code></a>s. The resolution can be cached by `resolve` for the <a href="angular2/di/Injector-class"><code>Injector</code></a> for
performance-sensitive code.

:markdown
Resolves bindings and creates an injector based on those bindings. This function is slower than the
corresponding `fromResolvedBindings` because it needs to resolve bindings first. See `resolve` for the
<a href="angular2/di/Injector-class"><code>Injector</code></a>.
Prefer `fromResolvedBindings` in performance-critical code that creates lots of injectors.
