/**
 * Class <code>DocFlavor</code> 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.</B> 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 <A HREF="http://www.ietf.org/rfc/rfc2046.txt">RFC 2046</A>)
 * 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.</B> 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() <CODE>Class.getName()</CODE>} method. 
 * (Thus the class name for <CODE>byte[]</CODE> is <CODE>"[B"</CODE>, for 
 * <CODE>char[]</CODE> it is <CODE>"[C"</CODE>.) 
 * </UL>
 * <P>
 * A <code>DocPrintJob</code> obtains its print data by means of interface 
 * {@link Doc Doc}. A <code>Doc</code> object lets the <code>DocPrintJob</code>
 * determine the doc flavor the client can supply.  A <code>Doc</code> object 
 * also lets the <code>DocPrintJob</code> obtain an instance of the doc flavor's 
 * representation class, from which the <code>DocPrintJob</code> then obtains 
 * the actual print data. 
 * <P>
 * <HR>
 * <H3>Client Formatted Print Data</H3>
 * There are two broad categories of print data, client formatted print data  
 * and service formatted print data. 
 * <P>
 * For <B>client formatted print data</B>, the client determines or knows the 
 * print data format.
 * For example the client may have a JPEG encoded image, a URL for
 * HTML code, or a disk file containing plain text in some encoding, 
 * possibly obtained from an external source, and
 * requires a way to describe the data format to the print service.
 * <p>
 * The doc flavor's representation class is a conduit for the JPS
 * <code>DocPrintJob</code> to obtain a sequence of characters or
 * bytes from the client. The 
 * doc flavor's MIME type is one of the standard media types telling how to 
 * interpret the sequence of characters or bytes. For a list of standard media 
 * types, see the Internet Assigned Numbers Authority's (IANA's) <A 
 * HREF="http://www.isi.edu/in-notes/iana/assignments/media-types/">Media Types 
 * Directory</A>. Interface {@link Doc Doc} provides two utility operations, 
 * {@link Doc#getReaderForText() getReaderForText} and 
 * {@link Doc#getStreamForBytes() getStreamForBytes()}, to help a 
 * <code>Doc</code> object's client extract client formatted print data. 
 * <P>
 * For client formatted print data, the print data representation class is 
 * typically one of the following (although other representation classes are 
 * permitted): 
 * <UL>
 * <LI>
 * Character array (<CODE>char[]</CODE>) -- The print data consists of the 
 * Unicde characters in the array.
 * <P>
 * <LI>
 * <code>String</code>  --  
 * The print data consists of the Unicode characters in the string.
 * <P>
 * <LI>
 * Character stream ({@link java.io.Reader java.io.Reader})
 * -- The print data consists of the Unicode characters read from the stream
 * up to the end-of-stream.
 * <P>
 * <LI>
 * Byte array (<CODE>byte[]</CODE>) -- The print data consists of the bytes in 
 * the array. The bytes are encoded in the character set specified by the doc 
 * flavor's MIME type. If the MIME type does not specify a character set, the 
 * default character set is US-ASCII. 
 * <P>
 * <LI>
 * Byte stream ({@link java.io.InputStream java.io.InputStream}) -- 
 * The print data consists of the bytes read from the stream up to the 
 * end-of-stream. The bytes are encoded in the character set specified by the 
 * doc flavor's MIME type. If the MIME type does not specify a character set, 
 * the default character set is US-ASCII. 

 * <LI>
 * Uniform Resource Locator ({@link java.net.URL URL})
 * -- The print data consists of the bytes read from the URL location.
 * The bytes are encoded in the character set specified by the doc flavor's
 * MIME type. If the MIME type does not specify a character set, the default
 * character set is US-ASCII. 
 * <P>
 * When the representation class is a URL, the print service itself accesses
 * and downloads the document directly from its URL address, without involving
 * the client. The service may be some form of network print service which
 * is executing in a different environment.
 * This means you should not use a URL print data flavor to print a 
 * document at a restricted URL that the client can see but the printer cannot 
 * see. This also means you should not use a URL print data flavor to print a 
 * document stored in a local file that is not available at a URL
 * accessible independently of the client.
 * For example, a file that is not served up by an HTTP server or FTP server.
 * To print such documents, let the client open an input stream on the URL
 * or file and use an input stream data flavor.
 * </UL>
 * <p>
 * <HR>
 * <h3>Default and Platform Encodings</h3>
 * <P>
 * For byte print data where the doc flavor's MIME type does not include a 
 * <CODE>charset</CODE> parameter, the Java Print Service instance assumes the 
 * US-ASCII character set by default. This is in accordance with
 * <A HREF="http://www.ietf.org/rfc/rfc2046.txt">RFC 2046</A>, which says the 
 * default character set is US-ASCII. Note that US-ASCII is a subset of
 * UTF-8, so in the future this may be widened if a future RFC endorses
 * UTF-8 as the default in a compatible manner.
 * <p>
 * Also note that this is different than the behaviour of the Java runtime 
 * when interpreting a stream of bytes as text data. That assumes the
 * default encoding for the user's locale. Thus, when spooling a file in local
 * encoding to a Java Print Service it is important to correctly specify
 * the encoding. Developers working in the English locales should
 * be particularly conscious of this, as their platform encoding corresponds
 * to the default mime charset. By this coincidence that particular
 * case may work without specifying the encoding of platform data.
 * <p>
 * Every instance of the Java virtual machine has a default character encoding
 * determined during virtual-machine startup and typically depends upon the
 * locale and charset being used by the underlying operating system. 
 * In a distributed environment there is no gurantee that two VM's share
 * the same default encoding. Thus clients which want to stream platform
 * encoded text data from the host platform to a Java Print Service instance
 * must explicitly declare the charset and not rely on defaults.
 * <p>
 * The preferred form is the official IANA primary name for an encoding.
 * Applications which stream text data should always specify the charset
 * in the mime type, which necessitates obtaining the encoding of the host
 * platform for data (eg files) stored in that platform's encoding.
 * A CharSet which corresponds to this and is suitable for use in a
 * mime-type for a DocFlavor can be obtained
 * from {@link DocFlavor#hostEncoding <CODE>DocFlavor.hostEncoding</CODE>}
 * This may not always be the primary IANA name but is guaranteed to be
 * understood by this VM.
 * For common flavors, the pre-defined *HOST DocFlavors may be used.
 * <p>
 * <p>
 * See <a href="../../java/lang/package-summary.html#charenc">
 * character encodings</a> for more information on the character encodings
 * supported on the Java platform.

 * <HR>
 * <h3>Recommended DocFlavors</h3>
 * <P>
 * The Java Print Service API does not define any mandatorily supported
 * DocFlavors.
 * However, here are some examples of MIME types that a Java Print Service
 * instance might support for client formatted print data.
 * 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.

 * <HR>
 * <H3>Service Formatted Print Data</H3>
 * <P>
 * For <B>service formatted print data</B>, the Java Print Service instance 
 * determines the print data format. The doc flavor's representation class 
 * denotes an interface whose methods the <code>DocPrintJob</code> 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"</CODE> 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

 * <H3>Pre-defined Doc Flavors</H3>
 * A Java Print Service instance is not <B><I>required</I></B> to support the 
 * following print data formats and print data representation classes.  In 
 * fact, a developer using this class should <b>never</b> 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>&#183;&nbsp;&nbsp;
 * <CODE>("text/plain", "java.io.InputStream")</CODE>
 * <BR>&#183;&nbsp;&nbsp;
 * <CODE>("text/plain; charset=us-ascii", "java.io.InputStream")</CODE>
 * <BR>&#183;&nbsp;&nbsp;
 * <CODE>("text/plain; charset=utf-8", "java.io.InputStream")</CODE>
 * <P>
 * <LI>
 * Renderable image objects. Specifically, the following doc flavor is
 * recommended to be supported: 
 * <BR>&#183;&nbsp;&nbsp;
 * <CODE>("application/x-java-jvm-local-objectref", "java.awt.image.renderable.RenderableImage")</CODE>
 * </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</H3>
 * <P>
 * Class DocFlavor in package javax.print.data is similar to class 
 * {@link java.awt.datatransfer.DataFlavor DataFlavor}. Class 
 * <code>DataFlavor</code>
 * 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</code>
 * 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</code>
 * 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</I> 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.
