Serializing the book Object to a File

SourcePro : XML Streams Module User’s Guide : Enhanced Streams : Example : Serializing the book Object to a File

First create a book object and serialize it out to a file. Because the XML format generated by XML streams is difficult to read, transform the output stream to a more easily-readable format.

int main()

{

using std::ofstream; //1

using std::ifstream;

using std::cout;

using std::endl;

book book1("To Love and Be Wise","Josephine Tey"); //2

book book2;

{

ofstream fout("book.xml"); //3

RWObjectOutputStream out = //4

RWEnhancedXmlObjectOutputStreamImp::make(fout);

out << book1; //5

}

//1 Indicates that certain variables refer to their counterparts in the STD namespace.

//2 Creates two book objects, one with data, one to hold the data when you restore the object later.

//3 Creates an ofstream for writing character data to a file.

//4 Sets up an enhanced XML output stream that includes support for a transformation.

//5 Serializes the book object to a file.
