Technical information

Wishlisting an entity works via entity reference. Drupal doesn't allow referencing multiple entity types on the same entity reference field, so this module uses an "wishlist item" entity, which references the wishlisted entity and gets referenced by the wishlist entity. For each referenceable entity type, a wishlist item bundle gets created automatically. API functions like

$wishlist->addToWishlist($product_entity);
$wishlist->removeFromWishlist($other_product_entity);

are provided, so you don't have to handle any entity creation and referencing by yourself.
