10.4.8 ConstantDef Interface

A ConstantDef object (shown below) defines a named constant.

module CORBA {
       interface ConstantDef : Contained {
             readonly attribute TypeCode       type;
             readonly attribute IDLType        type_def;
             readonly attribute any            value;
       };
       struct ConstantDescription {
              Identifier           name;
              RepositoryId         id;
              RepositoryId         defined_in;
              VersionSpec          version;
              TypeCode             type;
              any                  value;
      };
};

type

Specifies the TypeCode describing the type of the constant. The type of a constant must be one of the simple types (long, short, float, char, string, octet, and so on).

type_def

Identifies the definition of the type of the constant.

value

Contains the value of the constant, not the computation of the value (for example, the fact that it was defined as “1+2”).

The describe operation for a ConstantDef object returns a ConstantDescription.
