/**
|
|
* <code>DocFlavor</code> provides a description of the format in which the
|
|
* print data will be supplied in a print job to the print service.
|
|
* <p>
|
|
* A doc flavor consists of two parts:
|
|
* <ul>
|
|
* <li>
|
|
* The MIME type (Multipurpose Internet Mail Extensions types as described
|
|
* in RFC 2045/2046) specifying the media format of the print data.
|
|
* </li><li>
|
|
* The representation class name which is the fully qualified name of the
|
|
* class providing the print data to the print job. For example if the print
|
|
* data is supplied as a byte array the representation class name will be
|
|
* <code>"[B"</code> or for an input stream <code>"java.io.InputStream"</code>.
|
|
* </li>
|
|
* </ul>
|
|
* The <code>DocFlavor</code> class is therefore used in several places in the
|
|
* Java Print Service API. A print service provides its supported document
|
|
* flavors as an array of DocFlavor objects and a print job gets the flavor of
|
|
* its data to print from the <code>Doc</code> object provided as a DocFlavor
|
|
* instance.
|
|
* </p>
|
|
* <p>
|
|
* It has to be differentiated between <b>client formatted</b> and <b>service
|
|
* formatted</b> print data. Client formatted print data is already provided
|
|
* formatted by the client e.g. in an image format or as postscript. For
|
|
* service formatted print data, the Java Print Service instance produces
|
|
* the formatted print data. Here the doc flavor's representation class name
|
|
* does specify an interface instead of the actual print data source. The
|
|
* print service will call the methods of the given implementation of this
|
|
* interface with a special Graphics object capable of producing formatted
|
|
* print data from the graphics routines inside the interface methods.
|
|
* </p>
|
|
* <p>
|
|
* <h3>Client formatted print data document flavors</h3>
|
|
* The print service uses the representation class of the doc flavor to know
|
|
* how to retrieve the print data. If the representation class is a
|
|
* <code>URL</code> it will open the URL to read the print data from it. If it is
|
|
* a <code>byte[]</code> it will directly use the array and send it to the
|
|
* printer. There are predefined doc flavor as inner class for the most common
|
|
* representation class types:
|
|
* <ul>
|
|
* <li>Character arrays (<code>char[]</code>): The characters of the array
|
|
* represent the print data.</li>
|
|
* <li>Character streams (<code>java.io.Reader</code>): The whole characters
|
|
* read from the stream represent the print data.</li>
|
|
* <li>String (<code>java.lang.String</code>): The characters of the String
|
|
* represent the print data.</li>
|
|
* <li>Byte arrays (<code>byte[]</code>): The bytes of the array represent the
|
|
* print data. Encoding if text content is given in the mime type.</li>
|
|
* <li>Byte streams (<code>java.io.InputStream</code>): The whole bytes read
|
|
* from the stream represent the print data. If text content the encoding is
|
|
* specified in the mime type.</li>
|
|
* <li>Uniform Resource Locator (<code>java.net.URL</code>): The bytes read
|
|
* from the stream through opening of the URL represent the print data.
|
|
* If text content the encoding is specified in the mime type.</li></li>
|
|
* </ul>
|
|
* </p>
|
|
* <p>
|
|
* <h3>Service formatted print data document flavors</h3>
|
|
* The print service uses the provided object implementing the interface
|
|
* specified by the representation class to produce the formatted print data.
|
|
* The mime type of service formatted data is always
|
|
* <code>"application/x-java-jvm-local-objectref"</code> to signal the local
|
|
* reference to the print data object implementing the interface. Predefined
|
|
* doc flavor classes exist as an inner class for the three available interface
|
|
* to produce print data:
|
|
* <ul>
|
|
* <li>Pageable object (<code>java.awt.print.Pageable</code>): A pageable object
|
|
* is supplied to the print service. The print service will call the methods of
|
|
* the interface with a Grahics object to produce the formatted print data.</li>
|
|
* <li>Printable object (<code>java.awt.print.Printable</code>): A printable object
|
|
* is supplied to the print service. The print service will call the methods of
|
|
* the interface with a Grahics object to produce the formatted print data.</li>
|
|
* <li>Renderable Image object
|
|
* (<code>java.awt.image.renderable.RenderableImage</code>): A renderable image
|
|
* object is supplied to the print service. The print service calls methods of
|
|
* this interface to obtain the image to be printed.</li>
|
|
* </ul>
