Feature: #413 - Provide Product Traits

See Issue #413

Description

Products can have several features like categories and tags or files and images and some more. To ease the domain models in the extcode/cart-books, extcode/cart-events, and extcode/cart-products the extcode/cart extension provides some Traits.

• \Extcode\Cart\Domain\Model\Product\CategoryTrait

• \Extcode\Cart\Domain\Model\Product\FileAndImageTrait

• \Extcode\Cart\Domain\Model\Product\MeasureTrait

• \Extcode\Cart\Domain\Model\Product\ServiceAttributeTrait

• \Extcode\Cart\Domain\Model\Product\StockTrait

• \Extcode\Cart\Domain\Model\Product\TagTrait

Impact

Negative effects are not expected. The traits can also be used in own product extensions. With the use it is to be made certain that the __construct method is not called and in the class, which uses appropriate Traits then the ObjectStorages must initialize themselves.
