Atomic Simple Types

---

Atomic simple types include boolean, integer, double, decimal, and types derived from these base types. The classes generated for these types include a value member that can be assigned to directly. They also include a parameterized constructor that allows assignment through construction and an assignment operator that makes it possible to do assignment directly through the `=' sign without having to use the value member. This makes assignment compatible with the C case.

For example, the following simple integer type declaration:

   <xsd:simpleType name="EmployeeNumber">
 
      <xsd:restriction base="xsd:integer"/>
 
   </xsd:simpleType>
 

causes a class with the following constructors and assignment operator to be generated:

class EmployeeNumber : public OSBaseType {
 
public:
 
   OSINT32 value;
 
   EmployeeNumber ();
 
   EmployeeNumber (OSINT32 value);
 
   EmployeeNumber& operator= (OSINT32 value);
 

 

This makes it possible to assign an employee number in any of the following ways:

EmployeeNumber empno (33);
 

or

EmployeeNumber empno;
 
empno.value = 33;
 

or

EmployeeNumber empno;
 
empno = 33;
