ActionFilter
A simple kind of ActionRefiner which, given a request (of type R), may either immediately produce a Result (for example, an error), or continue its Action block with the same request. The critical (abstract) function is filter.

Abstract methods
Determine whether to process a request. This is the main method that an ActionFilter has to implement. It can decide to immediately intercept the request and return a Result (Some), or continue processing (None).

Value parameters
- request

the input request

- Returns
-
An optional Result with which to abort the request
Concrete methods
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).

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.
