public BaseFieldDefinition::setCardinality($cardinality) Sets the maximum number of items allowed for the field. Possible values are positive integers or FieldStorageDefinitionInterface::CARDINALITY_UNLIMITED. Parameters int $cardinality: The field cardinality. Return value $this File core/lib/Drupal/Core/Field/BaseFieldDefinition.php, line 273 Class BaseFieldDefinition A class for defining entity fields.

public BaseFieldDefinition::isQueryable() Determines whether the field is queryable via QueryInterface. Return value bool TRUE if the field is queryable.

public BaseFieldDefinition::setCustomStorage($custom_storage) Sets the storage behavior for this field. Parameters bool $custom_storage: Pass FALSE if the storage takes care of storing the field, TRUE otherwise. Return value $this Throws \LogicException Thrown if custom storage is to be set to FALSE for a computed field.

public BaseFieldDefinition::hasCustomStorage() Returns the storage behavior for this field. Indicates whether the entity type's storage should take care of storing the field values or whether it is handled separately; e.g. by the module providing the field. Return value bool FALSE if the storage takes care of storing the field, TRUE otherwise.

public BaseFieldDefinition::getTargetEntityTypeId() Returns the ID of the entity type the field is attached to. This method should not be confused with EntityInterface::getEntityTypeId() (configurable fields are config entities, and thus implement both interfaces): FieldDefinitionInterface::getTargetEntityTypeId() answers "as a field, which entity type are you attached to?". EntityInterface::getEntityTypeId() answers "as a (config) entity, what is your own entity type?". Return value string
