FieldAPIHandlerTrait::getFieldDefinition

protected FieldAPIHandlerTrait::getFieldDefinition()

Gets the field definition.

A View works on an entity type across bundles, and thus only has access to field storage definitions. In order to be able to use widgets and formatters, we create a generic field definition out of that storage definition.

Return value

\Drupal\Core\Field\FieldDefinitionInterface The field definition used by this handler.
