You +will need the ACE library[1] installed in order to build and run this +example. + +[1] http://www.cs.wustl.edu/~schmidt/ACE.html + +The example consists of the following files: + +library.xsd + XML Schema which describes a library of books. + +library.xml + Sample XML instance document. + +library.hxx +library.cxx + C++ types that represent the given vocabulary as well as data + representation stream insertion and extraction operations. These + are generated by XSD from library.xsd. Note that the + --generate-insertion and --generate-extraction options are used + to generate the insertion and extraction operations for ACE CDR + stream. + +driver.cxx + Driver for the example. It first calls one of the parsing functions + that constructs the object model from the input XML file. It then + saves the object model to ACE_OuputCDR and loads it back from + ACE_InputCDR. Additionally, it prints the resulting binary + representation as well as the content of the object model before + saving it to the CDR stream and after loading it from the CDR stream. + +To run the example on the sample XML instance document simply execute: + +$ ./driver library.xml diff --git a/xsd/examples/cxx/tree/binary/cdr/driver.cxx b/xsd/examples/cxx/tree/binary/cdr/driver.cxx new file mode 100644 index 0000000..ec1ff32 --- /dev/null +++ b/xsd/examples/cxx/tree/binary/cdr/driver.cxx @@ -0,0 +1,87 @@ +// file : examples/cxx/tree/binary/cdr/driver.cxx +// copyright : not copyrighted - public domain + +#include <memory> // std::auto_ptr +#include <cstring> // std::memcpy +#include <iostream> + +#include <ace/Log_Msg.h> // ACE_HEX_DUMP +#include <ace/CDR_Stream.h> + +// The following two headers define XSD-specific insertion/extraction +// operations for ACE CDR streams.
