* <H3>Service Formatted Print Data
* <P>
* For <B>service formatted print data, the Java Print Service instance
* determines the print data format. The doc flavor's representation class
* denotes an interface whose methods the <code>DocPrintJob invokes to
* determine the content to be printed -- such as a renderable image
* interface or a Java printable interface.
* The doc flavor's MIME type is the special value
* <CODE>"application/x-java-jvm-local-objectref" indicating the client
* will supply a reference to a Java object that implements the interface
* named as the representation class.
* This MIME type is just a placeholder; what's
* important is the print data representation class.
* <P>
* For service formatted print data, the print data representation class is
* typically one of the following (although other representation classes are
* permitted). Nested classes inside class DocFlavor declare predefined static
* constant DocFlavor objects for these example doc flavors; class DocFlavor's
* constructor can be used to create an arbitrary doc flavor.
* <UL>
* <LI>
* Renderable image object -- The client supplies an object that implements
* interface
* {@link java.awt.image.renderable.RenderableImage RenderableImage}. The
* printer calls methods
* in that interface to obtain the image to be printed.
* <P>
* <LI>
* Printable object -- The client supplies an object that implements interface
* {@link java.awt.print.Printable Printable}.
* The printer calls methods in that interface to obtain the pages to be
* printed, one by one.
* For each page, the printer supplies a graphics context, and whatever the
* client draws in that graphics context gets printed.
* <P>
* <LI>
* Pageable object -- The client supplies an object that implements interface
* {@link java.awt.print.Pageable Pageable}. The printer calls
* methods in that interface to obtain the pages to be printed, one by one.
* For each page, the printer supplies a graphics context, and whatever
* the client draws in that graphics context gets printed.

* <H3>Pre-defined Doc Flavors
* A Java Print Service instance is not <B>required to support the
* following print data formats and print data representation classes. In
* fact, a developer using this class should <b>never assume that a
* particular print service supports the document types corresponding to
* these pre-defined doc flavors. Always query the print service
* to determine what doc flavors it supports. However,
* developers who have print services that support these doc flavors are
* encouraged to refer to the predefined singleton instances created here.
* <UL>
* <LI>
* Plain text print data provided through a byte stream. Specifically, the
* following doc flavors are recommended to be supported:
* <BR>·
* <CODE>("text/plain", "java.io.InputStream")
* <BR>·
* <CODE>("text/plain; charset=us-ascii", "java.io.InputStream")
* <BR>·
* <CODE>("text/plain; charset=utf-8", "java.io.InputStream")
* <P>
* <LI>
* Renderable image objects. Specifically, the following doc flavor is
* recommended to be supported:
* <BR>·
* <CODE>("application/x-java-jvm-local-objectref", "java.awt.image.renderable.RenderableImage")
* </UL>
* <P>
* A Java Print Service instance is allowed to support any other doc flavors
* (or none) in addition to the above mandatory ones, at the implementation's
* choice.
* <P>
* Support for the above doc flavors is desirable so a printing client can rely
* on being able to print on any JPS printer, regardless of which doc flavors
* the printer supports. If the printer doesn't support the client's preferred
* doc flavor, the client can at least print plain text, or the client can
* convert its data to a renderable image and print the image.
* <P>
* Furthermore, every Java Print Service instance must fulfill these
* requirements for processing plain text print data:
* <UL>
* <LI>
* The character pair carriage return-line feed (CR-LF) means
* "go to column 1 of the next line."
* <LI>
* A carriage return (CR) character standing by itself means
* "go to column 1 of the next line."
* <LI>
* A line feed (LF) character standing by itself means
* "go to column 1 of the next line."
* <LI>
* </UL>
* <P>
* The client must itself perform all plain text print data formatting not
* addressed by the above requirements.
* <P>
* <H3>Design Rationale
* <P>
* Class DocFlavor in package javax.print.data is similar to class
* {@link java.awt.datatransfer.DataFlavor DataFlavor}. Class
* <code>DataFlavor
* is not used in the Java Print Service (JPS) API
* for three reasons which are all rooted in allowing the JPS API to be
* shared by other print services APIs which may need to run on Java profiles
* which do not include all of the Java Platform, Standard Edition.
* <OL TYPE=1>
* <LI>
* The JPS API is designed to be used in Java profiles which do not support
* AWT.
* <P>
* <LI>
* The implementation of class <code>java.awt.datatransfer.DataFlavor
* does not guarantee that equivalent data flavors will have the same
* serialized representation. DocFlavor does, and can be used in services
* which need this.
* <P>
* <LI>
* The implementation of class <code>java.awt.datatransfer.DataFlavor
* includes a human presentable name as part of the serialized representation.
* This is not appropriate as part of a service matching constraint.
* </OL>
* <P>
* Class DocFlavor's serialized representation uses the following
* canonical form of a MIME type string. Thus, two doc flavors with MIME types
* that are not identical but that are equivalent (that have the same
* canonical form) may be considered equal.
* <UL>
* <LI> The media type, media subtype, and parameters are retained, but all
* comments and whitespace characters are discarded.
* <LI> The media type, media subtype, and parameter names are converted to
* lowercase.
* <LI> The parameter values retain their original case, except a charset
* parameter value for a text media type is converted to lowercase.
* <LI> Quote characters surrounding parameter values are removed.
* <LI> Quoting backslash characters inside parameter values are removed.
* <LI> The parameters are arranged in ascending order of parameter name.
* </UL>
* <P>
* Class DocFlavor's serialized representation also contains the
* fully-qualified class <I>name of the representation class
* (a String object), rather than the representation class itself
* (a Class object). This allows a client to examine the doc flavors a
* Java Print Service instance supports without having
* to load the representation classes, which may be problematic for
* limited-resource clients.
* <P>

/**
* Class <code>DocFlavor encapsulates an object that specifies the
* format in which print data is supplied to a {@link DocPrintJob}.
* "Doc" is a short, easy-to-pronounce term that means "a piece of print data."
* The print data format, or "doc flavor", consists of two things:
* <UL>
* <LI>
* <B>MIME type. This is a Multipurpose Internet Mail Extensions (MIME)
* media type (as defined in <A HREF="http://www.ietf.org/rfc/rfc2045.txt">RFC
* 2045</A> and RFC 2046)
* that specifies how the print data is to be interpreted.
* The charset of text data should be the IANA MIME-preferred name, or its
* canonical name if no preferred name is specified. Additionally a few
* historical names supported by earlier versions of the Java platform may
* be recognized.
* See <a href="../../java/lang/package-summary.html#charenc">
* character encodings</a> for more information on the character encodings
* supported on the Java platform.
* <P>
* <LI>
* <B>Representation class name. This specifies the fully-qualified name of
* the class of the object from which the actual print data comes, as returned
* by the {@link java.lang.Class#getName() Class.getName()} method.
* (Thus the class name for <CODE>byte[] is | Description | Description | Description | Description |
|---|
