protected function TermStorageSchema::getEntitySchema in Zircon Profile 8

Same name and namespace in other branches

1. 8.0 core/modules/taxonomy/src/TermStorageSchema.php \Drupal\taxonomy\TermStorageSchema::getEntitySchema()

Gets the entity schema for the specified entity type.

Entity types may override this method in order to optimize the generated schema of the entity tables. However, only cross-field optimizations should be added here; e.g., an index spanning multiple fields. Optimizations that apply to a single field have to be added via SqlContentEntityStorageSchema::getSharedTableFieldSchema() instead.

Parameters

\Drupal\Core\Entity\ContentEntityTypeInterface $entity_type: The entity type definition.

bool $reset: (optional) If set to TRUE static cache will be ignored and a new schema array generation will be performed. Defaults to FALSE.

Return value

array A Schema API array describing the entity schema, excluding dedicated field tables.

Throws

\Drupal\Core\Field\FieldException

Overrides SqlContentEntityStorageSchema::getEntitySchema

File

core/modules/taxonomy/src/TermStorageSchema.php, line 22
