Service-Formatted Print Data

Rather than the client describing the print data format with a MIME type, the client can supply a Java object from which a print service determines the print data format. For example, the Java object can encapsulate a PostScript document. Instead of the client explicitly describing the document as PostScript with a MIME type, the client can wrap a reference to the document in a Java object, which the print service inspects to determine that the format is PostScript. Because the print data is delivered to the print service through the Java object, the class that the Java object implements is the representation class.

The DocFlavor class has an inner class called DocFlavor.SERVICE_FORMATTED that contains DocFlavor object constants representing service-formatted print data. Each of these constants has a MIME type of "application/x-java-jvm-local-objectref", which indicates that the client will supply a reference to a Java object implementing the interface named as the representation class.

The three DocFlavor object constants contained in DocFlavor.SERVICE_FORMATTED each represent a common representation class name used with service-formatted print data:
