## com.sas.servlet.tbeans.dataselectors.calculateditems.html
Class SimpleCalculatedItemSelector

    com.sas.servlet.tbeans.dataselectors.calculateditems.html.SimpleCalculatedItemSelector

All Implemented Interfaces:
  HttpActionProviderInterface, com.sas.beans.PropertyChangeSource, CompositeSelectorInterface, DataSelectorInterface, HttpDataSelectorInterface, com.sas.dataselectors.SelectorCloseInterface, com.sas.lang.ObjectDataInterface, com.sas.servlet.tbeans.AJAXControllerURLInterface, ComplexStyleInterface, CompositeComponentInterface, SelectorContainerStyleKeysInterface, SelectorContainerKeysInterface, FormViewInterface, RenderableInterface, TemplateInterface, com.sas.servlet.tbeans.TemplateKeyInterface, TransformationInterface, com.sas.util.WriteToPrintWriterInterface, java.io.Serializable

    public class SimpleCalculatedItemSelector

implements CompositeSelectorInterface

The SimpleCalculatedItemSelector is a TransformationBean™ that generates the appropriate HTML 4.0 and JavaScript to create a container class for the simple calculated item selector, a data selector used to manage calculated items created at run-time. The selector allows a user to create simple calculated columns or measures from a list of available data items. The simple calculated item selector supports the following operations: addition, subtraction, multiplication, and division. This selector provides the user interface for creating, updating, and deleting calculated items at run-time.

The SimpleCalculatedItemSelector is invoked from the menu bar on a relational or OLAP table view composite component. This visual provides a wrapper to the `SimpleCalculatedItemSelectorPanel` which provides the functionality for this selector.

Note that the toString() method on this class calls the `write` method, which may have undesirable side effects. See BaseTransformation.toString() for more information. Debuggers often use toString() to show the value of a variable, and this may cause unexpected behavior while debugging
