public interface DataContentHandler
DataContentHandlers
the framework can be extended to convert streams in to objects, and
to write objects to streams. Applications don't generally call the methods in DataContentHandlers directly. Instead, an application calls the equivalent methods in DataHandler. The DataHandler will attempt to find an appropriate DataContentHandler that corresponds to its MIME type using the current DataContentHandlerFactory. The DataHandler then calls through to the methods in the DataContentHandler.
