3. 10 core/lib/Drupal/Core/Entity/Entity/EntityFormDisplay.php \Drupal\Core\Entity\Entity\EntityFormDisplay::collectRenderDisplay()

Returns the entity_form_display object used to build an entity form.

Depending on the configuration of the form mode for the entity bundle, this can be either the display object associated with the form mode, or the 'default' display.

This method should only be used internally when rendering an entity form. When assigning suggested display options for a component in a given form mode, EntityDisplayRepositoryInterface::getFormDisplay() should be used instead, in order to avoid inadvertently modifying the output of other form modes that might happen to use the 'default' display too. Those options will then be effectively applied only if the form mode is configured to use them.

hook_entity_form_display_alter() is invoked on each display, allowing 3rd party code to alter the display options held in the display before they are used to generate render arrays.

Parameters

\Drupal\Core\Entity\FieldableEntityInterface $entity: The entity for which the form is being built.

string $form_mode: The form mode.

bool $default_fallback: (optional) Whether the default display should be used to initialize the form display in case the specified display does not exist. Defaults to TRUE.

Return value

\Drupal\Core\Entity\Display\EntityFormDisplayInterface The display object that should be used to build the entity form.
