ActionFunction

trait ActionFunction[-R[_], +P[_]] extends AnyRef

A builder for generic Actions that generalizes over the type of requests. An ActionFunction[R,P] may be chained onto an existing ActionBuilder[R] to produce a new ActionBuilder[P] using andThen. The critical (abstract) function is invokeBlock. Most users will want to use ActionBuilder instead.

R

the type of the request on which this is invoked (input)

P

the parameter type which blocks executed by this builder take (output)

Abstract Value Members

  1. abstract def executionContext: ExecutionContext

    returns

    The execution context to run the request in.

    protected
  2. abstract 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
