protected TermStorageSchema::getEntitySchema(ContentEntityTypeInterface $entity_type, $reset = FALSE)
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
