# Immutable Trait

This trait makes it super easy to turn an instance immutable or mutable.

## Installation

php-immutable-trait is installable via [Composer](http://getcomposer.org)

    composer require jclaveau/php-immutable-trait

## Usage

```php

class ImmutableObject

{

    use Immutable;

    // use SwitchableMutability; // This traits provides becomesMutable() and becomesImmutable()

    protected $property;

    public function setProperty($value)

    {

        // Just add these lines at the really beginning of methods supporting

        // immutability (setters mostly)

        if ($this->callOnCloneIfImmutable($result))

            return $result;

        // $this is now the new instance if it's immutable

        $this->property = $value;

        return $this;

    }

    public function getProperty()

    {

        return $this->property;

    }

}

$instance = new ImmutableObject;

$instance2 = $instance->setProperty('new value');

var_dump( $instance->getProperty() ); => null

var_dump( $instance2->getProperty() ); => 'new value'

```

## TODO

+ Profiles

+ PHP 7

+ Support immutability for private / protected methods? Should the dev handle it?

  Should we provide a simple protected API for it?
