TypedCallable
=============

[](#typedcallable)

Abstract PHP class, which allows to implement callables with signature check

Installation
============

[](#installation)

```
composer require czt08883/typed-callable dev-master

```

Usage
=====

[](#usage)

Define your own class extending TypedCallable

```
use Czt08883\TypedCallable\TypedCallable\TypedCallable;

class OnDataCallable extends TypedCallable
{
    /**
     * Implement "useTemplate()" abstract method.
     * This method must return a callable, which will
     * be used as a template for signature check.
     *
     * @return callable
     */
    public function useTemplate()
    {
        return function(SomeClass $a, array $b, $c){};
    }
}

```

In your other class, which requires typed callable:

- store this typed callable as a property
- invoke this typed callable on some event, passing some data

    class DataReceiverExample {

    ```
    /**
     * @var OnDataCallable
     */
    private $onDataCallback;

    /**
     * Use this typed callable as an argument in some function
     * to setup a callback
     */
    public function setOnDataCallback(OnDataCallable $callback)
    {
        $this->onDataCallback = $callback;
    }

    /**
     * Execute your callback on some event, passing proper parameters.
     * For example, on receiving data from external source
     */
     public function onData()
     {
        // ... receive some data and pass it to callback ...
        call_user_func(
            $this->onDataCallback,
            [
                new SomeClass,
                ['some','data','as','array'],
                "some string"
            ]
        );
     }

    ```

    }

Use your DataReceiverExample

```
  $dataReceiver = new DataReceiverExample();
  $dataReceiver->setOnDataCallback(
      new OnDataCallable(
         function (SomeClass $a, array $b, $c) {
            // just display it, for example
            echo "Yay, received some data.";
         }
      )
  );

  /* Simulate incoming data event:
   * This will invoke a callback, installed earlier. So output will be
   *     "Yay, received some data."
   */
  $dataReceiver->onData();

```

Now let us test callback with wrong signature. Following code will trigger TypedCallableSignatureMismatchException with following message: "Callable signature mismatch. Callable must be: function(SomeClass $a, array $b, $c){...}"

```
   $dataReceiver->setOnDataCallback(
        new OnDataCallable(
           function (SomeOtherClass $c) {
             // ... other actions, not important here
           }
        )
    );

```
