```
{
    "require": {
        "othercode/ddd-value-object": "*"
    }
}
```

Usage
-----

[](#usage)

Build a Value object is quite simple, you just need to extend the `ValueObject` Next, initialize the values in the constructor by using the `initialize` method. Finally, add invariant rules as protected method, using the prefix `invariant` (this prefix can be customized) and execute them with the `checkInvariants` method.

```
