<itemvalue="Performs the [action] on each header. The [action] function is called with each header's name and a list of the header's values. The casing of the name string is determined by the last [add] or [set] operation for that particular header, which defaults to lower-casing the header name unless explicitly set to preserve the case."/>
<itemvalue="Sets the header [name] to [value]. Removes all existing values for the header named [name] and then [add]s [value] to it."/>
<itemvalue="Invokes [action] on each element of this iterable in iteration order. Example: ```dart final numbers = <int>[1, 2, 6, 7]; numbers.forEach(print); 1 2 6 7 ```"/>
<itemvalue="Executes [action] on each element of this stream. Completes the returned [Future] when all elements of this stream have been processed. If this stream emits an error, or if the call to [action] throws, the returned future completes with that error, and processing stops."/>
<itemvalue="Waits for multiple futures to complete and collects their results. Returns a future which will complete once all the provided futures have completed, either with their results, or with an error if any of the provided futures fail. The value of the returned future will be a list of all the values that were produced in the order that the futures are provided by iterating [futures]. If any future completes with an error, then the returned future completes with that error. If further futures also complete with errors, those errors are discarded. If `eagerError` is true, the returned future completes with an error immediately on the first error from one of the futures. Otherwise all futures must complete before the returned future is completed (still with the first error; the remaining errors are silently dropped). In the case of an error, [cleanUp] (if provided), is invoked on any non-null result of successful futures. This makes it possible to `cleanUp` resources that would otherwise be lost (since the returned future does not provide access to these values). The [cleanUp] function is unused if there is no error. The call to [cleanUp] should not throw. If it does, the error will be an uncaught asynchronous error."/>
<itemvalue="Performs an action for each element of the iterable, in turn. The [action] may be either synchronous or asynchronous. Calls [action] with each element in [elements] in order. If the call to [action] returns a `Future<T>`, the iteration waits until the future is completed before continuing with the next element. Returns a [Future] that completes with `null` when all elements have been processed. Non-[Future] return values, and completion-values of returned [Future]s, are discarded. Any error from [action], synchronous or asynchronous, will stop the iteration and be reported in the returned [Future]."/>
<itemvalue="Copies this file. If [newPath] is a relative path, it is resolved against the current working directory ([Directory.current]). Returns a `Future<File>` that completes with a [File] for the copied file. If [newPath] identifies an existing file, that file is removed first. If [newPath] identifies an existing directory, the operation fails and the future completes with an exception."/>
<itemvalue="NOTE: By default, the Runner class does not use the `MirrorsReflector`, or any reflector, by default. If your application is using any sort of functionality reliant on annotations or reflection, either include the MirrorsReflector, or use a static reflector variant. The following use cases require reflection: Use of Controllers, via @Expose() or @ExposeWS() Use of dependency injection into constructors, whether in controllers or plain `container.make` calls Use of the `ioc` function in any route The `MirrorsReflector` from `package:angel_containermirrors.dart` is by far the most convenient pattern, so use it if possible. However, the following alternatives exist: Generation via `package:angel_container_generator` Creating an instance of `StaticReflector` Manually implementing the `Reflector` interface (cumbersome; not recommended) As of January 4th, 2018, the documentation has not yet been updated to state this, so in the meantime, visit the Angel chat for further questions: https:gitter.imangel_dartdiscussion"/>
<itemvalue="Modifies a package on the filesystem in order to remove dart:mirrors from the package. A copy of this compiler's package will be written to [destinationDirectory]. This method is overridden to modify the contents of that directory to remove all uses of dart:mirrors. Packages should export their [Compiler] in their main library file and only import mirrors in files directly or transitively imported by the Compiler file. This method should remove that export statement and therefore remove all transitive mirror imports."/>
