Bitrix Framework

Operation is based on the same logic as for EO_, and for Objects. Each entity has its own Collection class, inherited from Bitrix\Main\ORM\Objectify\Collection. The Book entity will have the EO_Book_Collection view by default. To set your own class, create a descendants for this class and designate it in the Table entity class:

//File bitrix/modules/main/lib/test/typography/books.php

namespace Bitrix\Main\Test\Typography;

class Books extends EO_Book_Collection
{
}

//File bitrix/modules/main/lib/test/typography/booktable.php

namespace Bitrix\Main\Test\Typography;

class BookTable extends Bitrix\Main\ORM\Data\DataManager
{
	public static function getCollectionClass()
	{
		return Books::class;
	}
	//...
}

Now the method fetchCollection will return the collection Bitrix\Main\Test\Typography\Books of class objects Bitrix\Main\Test\Typography\Book. Annotations allow for IDE to create hints, simplifying the developer's work.
