function hook_entity_type_alter

hook_entity_type_alter(array &$entity_types)

Alter the entity type definitions.

Modules may implement this hook to alter the information that defines an entity type. All properties that are available in \Drupal\Core\Entity\Annotation\EntityType and all the ones additionally provided by modules can be altered here.

Do not use this hook to add information to entity types, unless one of the following is true:

• You are filling in default values.
• You need to dynamically add information only in certain circumstances.
• Your hook needs to run after hook_entity_type_build() implementations.

Use hook_entity_type_build() instead in all other cases.

Parameters

\Drupal\Core\Entity\EntityTypeInterface[] $entity_types: An associative array of all entity type definitions, keyed by the entity type name. Passed by reference.
