org.eclipse.persistence.oxm.XMLContext
public class XMLContext
An XMLContext is created based on EclipseLink sessions or projects and can then used to create instances of XMLMarshaller, XMLUnmarshaller and XMLValidator.
There are constructors to create an XMLContext with a single EclipseLink project or with a String which is a single EclipseLink session name or a ':' separated list of EclipseLink session names.
Code Sample
XMLContext context = new XMLContext("mySessionName");
XMLMarshaller marshaller = context.createMarshaller();
XMLUnmarshaller unmarshaller = context.createUnmarshaller();
XMLValidator validator = context.createValidator();
The XMLContext is thread-safe. If multiple threads accessing the same XMLContext object request an XMLMarshaller, each will receive their own instance of XMLMarshaller, so any state that the XMLMarshaller maintains will be unique to that process. The same is true of instances of XMLUnmarshaller and XMLValidator.
