Character String Types

---

Character string types are derived from the built-in base class OSXMLStringClass. This class is in turn derived from the OSXMLSTRING C struct type which contains a value member character pointer variable.

An example of the constructors and assignment operators generated for a character string type is shown for the following definition:

   <xsd:simpleType name="Date">
      <xsd:restriction base="xsd:string"/>
   </xsd:simpleType>

The C++ constructors and assignment operators generated for this definition are as follows:

class EXTERN Date : public OSXMLStringClass {
public:
   Date ();
   Date (const OSUTF8CHAR* value);
   Date (const char* value);
   Date& operator= (const OSUTF8CHAR* value);
   Date& operator= (const char* value);

Note that constructors and operators are available that allow strings to be specified as either standard C character strings or as UTF-8 strings.

Assignment of strings always causes a deep-copy of the character data to be done.
