{@link org.exolab.castor.xml.Marshaller} marshalls a Java object into an XML document.
{@link org.exolab.castor.xml.Unmarshaller} unmarshalls an XML document back into a Java
object.
The following example unmarshals the XML document product.xml into a
Product object, performs simple changes to the object and then marshals it
back into an XML document.
Product prod;
File file;
file = new File( "product.xml" );
// Unmarshal the document into an object
prod = (Product) Unmarshaller.unmarshal( Product.class, new FileReader( file ) );
// A 25% mark down for each product and mark as sale
prod.markDown( 0.25 );
prod.setOnSale( true );
// Marshal the object into a document
Marshaller.marshal( Product, new FileWriter( file ) );
In addition to static methods, marshaller objects can be created and set with a variety
of options affecting how they will operation. The above example adapted to use a specific
mapping file:
Mapping map;
Unmarshaller umr;
Marshaller mar;
// Load the specified mapping file
map = new Mapping();
map.loadMapping( "mapping.xml" );
// Unmarshal the document into an object
umr = new Unmarshaller( Product.class );
umr.setMapping( mapping );
prod = (Product) umr.unmarshal( new FileReader( file ) );
: : :
// Marshal the object into a document
mar = new Marshaller( new FileWriter( file ) );
mar.setMapping( mapping );
mar.marshal( Product );
