This module is now part of the Developer Suite project and will be minimally maintained (bug fixes only).

Provides a plugin based system to alter entity type classes. It currently support overriding Node, User and File entity type classes.

Introduction

Typically you would want to extend entity type classes to create your own getters and setters or to override/extend the entity parents methods. By creating custom getters and setters on Drupal fields (such as `title`) you are able to provide doc blocks which in turn can help during development.

While powerful, overriding entity type classes is an advanced undertaking and potentially can break your site hard and fast. I would strongly recommend using this module only if you fully understand what you are doing.

Example (overriding the Node type class)

1. Create a new Node class (for example ArticleNode) and extend the \Drupal\node\Entity\Node class.

2. Create a new EntityTypeClass plugin in \Drupal\my_module\Plugin\EntityTypeClass and extend the \Drupal\entity_type_class\Storage\NodeStorage class (the other options for now are the UserStorage and FileStorage classes).

3. Decorate the class with the @EntityTypeClass annotation and provide the id, entity and label. The entity should be the system name of the Entity, in this case 'node'. In your custom plugin you are required to implement the getEntityTypeClass() method. This method should return the fully qualified class name of your custom Entity class.

<?php

namespace Drupal\my_module\Plugin\EntityTypeClass;

use Drupal\entity_type_class\Storage\NodeStorage;
use Drupal\node\Entity\Node;
use Drupal\my_module\Entity\ArticleNode;
use Drupal\my_module\Entity\PageNode;

/**
 * Class NodeTypeStorage.
 *
 * @EntityTypeClass(
 *   id = "node_type_class",
 *   entity = "node",
 *   label = @Translation("Node type class"),
 * )
 */
class NodeTypeClass extends NodeStorage {

  /**
   * Returns the entity class by type.
   *
   * @param string $type
   *   The entity type.
   *
   * @return string
   *   The entity class.
   */
  public function getEntityTypeClass($type) {
    switch ($type) {
      case 'article':
        return ArticleNode::class;

      case 'page':
        return PageNode::class;
    }

    return Node::class;
  }

}
