It presents the complex case where the customized types are +inherited from in the same schema. For the simple case see the contacts +example. For more information on the C++/Tree mapping customization see +the C++/Tree Mapping Customization Guide[1]. + +[1] http://wiki.codesynthesis.com/Tree/Customization_guide + +The example consists of the following files: + +people.xsd + XML Schema definition for a simple people database. + +people.xml + Sample XML instance document. + +people-fwd.hxx +people.hxx +people.ixx +people.cxx + C++ types that represent the given vocabulary and a set of parsing + functions that convert XML instance documents to a tree-like in-memory + object model. + + These files are generated by the XSD compiler from people.xsd using the + following command line: + + xsd cxx-tree --generate-forward --generate-polymorphic \ + --polymorphic-type person \ + --custom-type "person=person_impl<person_base>/person_base" \ + --custom-type "superman=superman_impl<superman_base>/superman_base" \ + --custom-type "batman=batman_impl<batman_base>/batman_base" \ + --fwd-prologue '#include "people-custom-fwd.hxx"' \ + --hxx-prologue '#include "people-custom.hxx"' people.xsd + + The --custom-type option is used to customize the person, superman, and + batman types. Generation of the people-fwd.hxx forward declaration + file is requested with the --generate-forward option. Note also that + we use the --generate-polymorphic command line option as well as + --polymorphic-type to mark the type hierarchy starting with the + person type as polymorphic. + +people-custom-fwd.hxx + Header file which forward-declares our own person, superman, and batman + as class templates. It is included at the beginning of people-fwd.hxx + using the --fwd-prologue option. + +people-custom.hxx + Header file which defines our own person, superman, and batman class + templates by inheriting from the generated person_base, superman_base, + and batman_base. It is included at the beginning of people.hxx using + the --hxx-prologue option. + +people-custom.cxx + Source file which contains the implementations and instantiations of + our person, superman, and batman class templates. + +driver.cxx + Driver for the example. It first calls one of the parsing functions + that constructs the object model from the input file. It then prints + the database to STDERR. + +To compile and link the example manually from the command line we can use +the following commands (replace 'c++' with your C++ compiler name): + +c++ -c people.cxx +c++ -c people-custom.cxx +c++ -c driver.cxx +c++ -o driver driver.o people.o people-custom.o -lxerces-c + +To run the example on the sample XML instance document execute: + +./driver people.xml |
