Simple trait to create enumeration classes.

Separate your enumerations into standalone classes and validate through your application that you are passing valid enumeration values.

Installation
------------

[](#installation)

Recommended to install using composer:

`composer require richard-ejem/enum`

Example
-------

[](#example)

```
class UserRole
{
    use \Ejem\Enum\EnumTrait;

    const GUEST = 'guest';
    const USER = 'user';
    const ADMIN = 'admin';
}

class User
{
    /** @var string UserRole enum */
    private $role;

    /** @throws \Ejem\Enum\InvalidEnumValueException */
    public function __construct(string $role)
    {
        $this->setRole($role);
    }

    public function getRole(): string
    {
        return $this->role;
    }

    /** @throws \Ejem\Enum\InvalidEnumValueException */
    public function setRole(string $role): void
    {
        UserRole::assertValidValue($role);
        $this->role = $role;
    }

    // ... more user stuff
}
```

Other features
--------------

[](#other-features)

```
// Validate without throwing exception.
// imagine you are importing users from an old system,
// setting all unsupported roles to GUEST:

$role = UserRole::isValidValue($row['role']) ? $row['role'] : UserRole::GUEST;

// Retrieve all possible values.
// Assign random color to a shape

$values = Color::getPossibleValues();
$shape->setColor($values[mt_rand(0, count($values)-1)]);
```
