Chain of Responsibility Bundle
==============================

[](#chain-of-responsibility-bundle)

A simple bundle that helps to integrate a chain of responsibility pattern through Symfony (3.3 and onwards supported). PHP 7.1 is required.

To install it through composer, you just need to require the `taluu/chain-of-responsibility-bundle` package. Other methods (zip, ... and so on) are supported but you're on your own. :P

Howto
-----

[](#howto)

To declare a chain of responsibility, each items *must* implement the `ChainOfResponsibility\LinkInterface` interface, declaring a successor (if there is one). How the object is executed is your concern. :}

An `AbstractLink` is given if you want to just implement a simple Chain of Responsibility pattern. Just extend it, and just implement the `doHandle` method.

Once you have your chained services, all you have to do is specify them in the bundle's configuration :

```
chain_of_responsibility:
    my_first_chain:
        - foo_service
        - Bar\Baz
        # - ...

    my_second_chain:
        - Bar\Baz
        - baz_service
        # - ...

    # ... and so on
```

The items are services identifiers, so these should be declared.

### Injecting Chains

[](#injecting-chains)

In the case you would want to inject the chains, the tip of each chain is aliased to a `chain_of_responsibility.chains.{{ name }}` (e.g `chain_of_responsibility.chains.my_first_chain`). So use that identifier to inject the correct chain.

Tests
-----

[](#tests)

Tested through PHPUnit 6. So just run the tests and it should be all green. :}
