Internal

Test programs:: tAttribute

Etymology

"AttValue" is a contraction of "Attribute Value"

Synopsis

AttValue provides type identification services for use in the Attribute classes.

Example

AttValue can be used to provide an enumeration which identifies the type of a variable, for example:

 Int i;
 if (AttValue::whatType(&i) != AttValue::AtInt) {
 throw(AipsError(String("Incorrect type identification in AttValue")));
 }

Motivation

This is a support class to unify type identification for the various Attribute classes.

To Do

Consider using global whatType function instead of this class.
