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:

casacore::Int i;
if (AttValue::whatType(&i) != AttValue::AtInt) {
throw(casacore::AipsError(casacore::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.
