Compose this ActionFunction with another, with this one applied first.

Constructs an Action with default content, and no request parameter.

For example:

val hello = Action {
  Ok("Hello!")
}

Constructs an Action with default content.

For example:

val echo = Action { request =>
  Ok("Got request [" + request + "]")
}

Constructs an ActionBuilder with the given BodyParser. The result can then be applied directly to a block.

For example:

val echo = Action(parse.anyContent) { request =>
  Ok("Got request [" + request + "]")
}

Constructs an Action with the given BodyParser that returns a future of a result.

For example:

val hello = Action.async(parse.anyContent) { request =>
  ws.url(request.getQueryString("url").get).get().map { r =>
    if (r.status == 200) Ok("The website is up") else NotFound("The website is down")
  }
}

Constructs an Action that returns a future of a result, with default content.

For example:

val hello = Action.async { request =>
  ws.url(request.getQueryString("url").get).get().map { r =>
    if (r.status == 200) Ok("The website is up") else NotFound("The website is down")
  }
}

Constructs an Action that returns a future of a result, with default content, and no request parameter.

For example:

val hello = Action.async {
  ws.url("http://www.playframework.com").get().map { r =>
    if (r.status == 200) Ok("The website is up") else NotFound("The website is down")
  }
}

Compose another ActionFunction with this one, with this one applied last.

Compose the action with other actions. This allows mixing in of various actions together.

Compose the parser. This allows the action builder to potentially intercept requests before they are parsed.

Invoke the block. This is the main method that an ActionBuilder has to implement, at this stage it can wrap it in any other actions, modify the request object or potentially use a different class to represent the request.
