Can I access changed parameters in an after/around plugin?

Question

I want to access a parameter of a method in an after plugin. The value of the parameter has been changed inside the original method, and I want to access the modified value. Example:

class vendorClass
{
    function paintBlue($room, $options)
    {
        // ...
        $options['color'] = 'light green';
    }
}

Now, my plugin looks like this:

class myPerfectMagentoPlugin
{
    public function __construct()
    {
    }

    public function afterPaintBlue($subject, $result, $room, $options)
    {
          // This $options array does not contain the color value:
          var_dump($options);
    }
}

How can I access the modified content of the $options variable in an after plugin?

Answer 1

There is no way to access that value in either an after or around plugin.

Answer 2

@shawn-abramson, right but if you do some changes at the original method then you can access the parameters of the change at around, after plugin.

If you pass this two-parameters ($room, $options) with a return of original function then you can data of both $room, $options at around and after plugin.

Original Method:

class vendorClass
{
    function paintBlue($room, $options)
    {
        // ...
        $options['color'] = 'light green'; 

        // Passing in array variable
        return [
            'room' => $room,
            'options'   => $options)
        ];
    }
}

After Plugin method:

class myPerfectMagentoPlugin
{
    public function __construct()
    {
    }

    public function afterPaintBlue($subject, $result, $room, $options)
    {
          $modifiedRoom =$result['room'];
          $modifiedOptions =$result['options'];
    }
}

Around Plugin Method

class myPerfectMagentoPlugin
{
    public function __construct()
    {
    }

    public function aroundPaintBlue($subject, \Callable $proceed, $room, $options)
    {
        // run original Method
        $result = $proceed($room, $options);    

        $modifiedRoom =$result['room'];
        $modifiedOptions =$result['options'];
    }
}
