Usage example
=============

[](#usage-example)

```
use alcamo\decorator\Decorator;
use Ds\Set;

class SetWithSum extends Decorator implements \Countable, \IteratorAggregate
{
    public function __construct($values)
    {
        parent::__construct(new Set($values));
    }

    public function getSum(): int
    {
        $result = 0;

        foreach ($this as $value) {
            $result += $value;
        }

        return $result;
    }
}

$set = new SetWithSum([ 42, 42, 7]);

echo "Count: " . count($set) . "\n";

echo "Sum: " . $set->getSum() . "\n";

```

This will output:

```
Count: 2
Sum: 49

```

Overview
========

[](#overview)

The trait `DecoratorTrait` implements the [Decorator pattern](https://en.wikipedia.org/wiki/Decorator_pattern) for an arbitrary object. The class `Decorator` uses this trait.

As in the example above, this can be used to create a class that adds functionality to a class when creating a derived class is not possible.

All functionality of the enclosed object is exposed by the decorator so that the decorator behaves just as the enclosed object, supporting, for instance, the Countable, Iterator or ArrayAccess interface.

The trait `MultiDecoratedTrait` offers a means to add multiple decorators to an object, indexed by their class nane. `MultiDecoratedArrayAccessTrait` is buil on top of this and allows to access the decorators via ArrayAccess methods.

See the doxygen documentation for details.
