IOptionTag is the tag handler class for the sas:IOption custom tag IOptionTag is invoked by the JSP page to evaluate the sas:IOption custom tag during the execution of the page. Tag handler methods are called by the JSP page implementation class at various points during the evaluation of the tag. The tag handler methods in turn call methods on the underlying Transformation Bean object, IOption, to execute the methods.

If you need to extend or modify the functionality of the sas:IOption custom tag, you can subclass this tag handler class.
