com.google.visualization.datasource.query.scalarfunction.ScalarFunction
A scalar function. A scalar function can have any arity, including 0, and can also have dynamic arity. It must always produce a single value. The return type of such a function may depend on the number and types of its arguments but never on their values. An instance of a class that implements this interface can be used within a ScalarFunctionColumn. @author Liron L.
