Manages entity type plugin definitions.

Each entity type definition array is set in the entity type's annotation and altered by hook_entity_type_alter().

Do not use hook_entity_type_alter() 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.
