Arbiter
=======

[](#arbiter)

An Action system for Action-Domain-Responder.

This package is installable and PSR-4 autoloadable via Composer as `arbiter/arbiter`.

Alternatively, download a release or clone this repository, then map the `Arbiter\` namespace to the package `src/` directory.

This package requires PHP 5.5 or later; it has been tested on PHP 5.6, PHP 7, and HHVM. You should use the latest available version of PHP as a matter of principle.

To run the tests, issue `composer install` to install the test dependencies, then issue `phpunit`.

---

An *Action* value object is composed of three elements:

- an `$input` callable: this collects input from the incoming *ServerRequestInterface* and converts it to an array of parameters suitable for `call_user_func_array()`;
- a `$domain` callable: this is invoked via `call_user_func_array()` using the array of parameters provided by the `$input` callable; and
- a `$responder` callable: this is invoked with the incoming *ServerRequestInterface*, the outgoing *ResponseInterface*, and the result (or "payload") returned by the `$domain` callable.

Call the *ActionHandler* `handle()` method with the *Action*, a *ServerRequestInterface*, and a *ResponseInterface*. The *ActionHandler* then acts as a mediator to direct the interaction between the three callables, and returns a modified *ResponseInterface*.
