As a result there - is a number of Schema constructs, techniques, and styles that don't - have appropriate counterparts in C++. This document presents a list - of do's and don'ts that will help ensure your schemas, when translated - by XSD, result in C++ code that is enjoyable to work with.</p> - - - <h1><a name="global_element">Don't define a global element which is not - a valid document root</a></h1> - - <p>Instead of</p> - - <pre> -<xsd:element name="author" type="Author"/> - -<xsd:complexType name="Book"> - <xsd:sequence> - <xsd:element ref="author"/> - </xsd:sequence> -</xsd:complexType> - </pre> - - <p>Write</p> - - <pre> -<xsd:complexType name="Book"> - <xsd:sequence> - <xsd:element name="author" type="Author"/> - </xsd:sequence> -</xsd:complexType> - </pre> - - <p>Any globally-defined element is a potential document root. For every - such element XSD generates a set of overloaded parsing - functions. If you cannot change your schema, consider using the - <code>--root-element-*</code> options to specify which global - element(s) are actual document root(s).</p> - - - - <h1><a name="same_local">Don't name a type and an element/attribute of - this type with the same name</a></h1> - - <p>Instead of</p> - - <pre> -<xsd:complexType name="name"> - <xsd:sequence> - <xsd:element name="name" type="xsd:string"/> - </xsd:sequence> - <xsd:attribute name="lang" type="xsd:language"/> -</xsd:complexType> - </pre> - - <p>Write</p> - - <pre> -<xsd:complexType name="Name"> - <xsd:sequence> - <xsd:element name="name" type="xsd:string"/> - </xsd:sequence> - <xsd:attribute name="lang" type="xsd:language"/> -</xsd:complexType> - </pre> - - <p>Use of a class name as a member function name within this class is - illegal in C++. XSD will resolve such conflicts by renaming - the conflicting member function.

XSD maps them to the - <code>long long</code> and <code>unsigned long long</code> C++ - types. In most cases you would prefer to use either - <code>xsd:int/xsd:unsignedInt</code> (32 bit, maps to C++ - <code>int/unsigned int</code>) or - <code>xsd:long/xsd:unsignedLong</code> (64 bit, maps to C++ - <code>long long/unsigned long long</code>). - </p> - - <h1><a name="int">Use <code>xsd:int/xsd:unsignedInt</code> for 32 bit - integers</a></h1> - - <p>XML Schema built-in types <code>long</code> and - <code>unsignedLong</code> are 64 bit wide so use 32 bit <code>int</code> - and <code>unsignedInt</code> unless you meant 64 bit.</p> - - </div> - <div id="footer"> - ©2005-2010 <a href="http://codesynthesis.com">CODE SYNTHESIS TOOLS CC</a> - - <div id="terms"> - Permission is granted to copy, distribute and/or modify this - document under the terms of the - <a href="http://codesynthesis.com/licenses/fdl-1.2.txt">GNU Free - Documentation License, version 1.2</a>; with no Invariant Sections, - no Front-Cover Texts and no Back-Cover Texts. - </div> - </div> - -</div> - - -</body> -</html> |
