- final def invokeBlock[A](request: R[A], block: (P[A]) => Future[Result]): Future[Result]
Invoke the block.
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.
- request
The request
- block
The block of code to invoke
- returns
A future of the result

- final def refine[A](request: R[A]): Future[Either[Result, P[A]]]
Determine how to process a request.
Determine how to process a request. This is the main method than an ActionRefiner has to implement. It can decide to immediately intercept the request and return a Result (Left), or continue processing with a new parameter of type P (Right).
- request
the input request
- returns
Either a result or a new parameter to pass to the Action block
- Definition Classes
- → ActionRefiner
A simple kind of ActionRefiner which, given a request (of type R), unconditionally transforms it to a new parameter type (P) to be passed to its Action block. The critical (abstract) function is transform.
