-/**
- * A {@code DataFlavor} provides meta information about data. {@code DataFlavor}
- * is typically used to access data on the clipboard, or during
- * a drag and drop operation.
- * <p>
- * An instance of {@code DataFlavor} encapsulates a content 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>.
- * A content type is typically referred to as a MIME type.
- * <p>
- * A content type consists of a media type (referred
- * to as the primary type), a subtype, and optional parameters. See
- * <a href="http://www.ietf.org/rfc/rfc2045.txt">RFC 2045</a>
- * for details on the syntax of a MIME type.
- * <p>
- * The JRE data transfer implementation interprets the parameter &quot;class&quot;
- * of a MIME type as <B>a representation class</b>.
- * The representation class reflects the class of the object being
- * transferred. In other words, the representation class is the type of
- * object returned by {@link Transferable#getTransferData}.
- * For example, the MIME type of {@link #imageFlavor} is
- * {@code "image/x-java-image;class=java.awt.Image"},
- * the primary type is {@code image}, the subtype is
- * {@code x-java-image}, and the representation class is
- * {@code java.awt.Image}. When {@code getTransferData} is invoked
- * with a {@code DataFlavor} of {@code imageFlavor}, an instance of
- * {@code java.awt.Image} is returned.
- * It's important to note that {@code DataFlavor} does no error checking
- * against the representation class. It is up to consumers of
- * {@code DataFlavor}, such as {@code Transferable}, to honor the representation
- * class.
- * <br>
- * Note, if you do not specify a representation class when
- * creating a {@code DataFlavor}, the default
- * representation class is used. See appropriate documentation for
- * {@code DataFlavor}'s constructors.
- * <p>
- * Also, {@code DataFlavor} instances with the &quot;text&quot; primary
- * MIME type may have a &quot;charset&quot; parameter. Refer to
- * <a href="http://www.ietf.org/rfc/rfc2046.txt">RFC 2046</a> and
- * {@link #selectBestTextFlavor} for details on &quot;text&quot; MIME types
- * and the &quot;charset&quot; parameter.
- * <p>
- * Equality of {@code DataFlavors} is determined by the primary type,
- * subtype, and representation class. Refer to {@link #equals(DataFlavor)} for
- * details. When determining equality, any optional parameters are ignored.
- * For example, the following produces two {@code DataFlavors} that
- * are considered identical:
- * <pre>
- *   DataFlavor flavor1 = new DataFlavor(Object.class, &quot;X-test/test; class=&lt;java.lang.Object&gt;; foo=bar&quot;);
- *   DataFlavor flavor2 = new DataFlavor(Object.class, &quot;X-test/test; class=&lt;java.lang.Object&gt;; x=y&quot;);
- *   // The following returns true.
- *   flavor1.equals(flavor2);
- * </pre>
- * As mentioned, {@code flavor1} and {@code flavor2} are considered identical.
- * As such, asking a {@code Transferable} for either {@code DataFlavor} returns
- * the same results.
- * <p>
- * For more information on using data transfer with Swing see
- * the <a href="http://docs.oracle.com/javase/tutorial/uiswing/dnd/index.html">
- * How to Use Drag and Drop and Data Transfer</a>,
- * section in <em>Java Tutorial</em>.

-     * <li>"text/plain"
-     * <li>"text/&lt;other&gt;"

-     * <p>For example, "text/sgml" will be selected over
-     * "text/html", and <code>DataFlavor.stringFlavor</code> will be chosen
-     * over <code>DataFlavor.plainTextFlavor</code>.
-     * <p>
-     * If two or more flavors share the best MIME type in the array, then that
-     * MIME type will be checked to see if it supports the charset parameter.
-     * <p>
-     * The following MIME types support, or are treated as though they support,
-     * the charset parameter:
-     * <ul>
-     * <li>"text/sgml"
-     * <li>"text/xml"
-     * <li>"text/html"
-     * <li>"text/enriched"

-     * <li>"text/calendar"
-     * <li>"application/x-java-serialized-object"
-     * <li>"text/plain"

-     * The following MIME types do not support, or are treated as though they
-     * do not support, the charset parameter:
-     * <ul>
-     * <li>"text/rtf"
-     * <li>"text/tab-separated-values"
-     * <li>"text/t140"

-     * </ul>
-     * For "text/&lt;other&gt;" MIME types, the first time the JRE needs to
-     * determine whether the MIME type supports the charset parameter, it will
-     * check whether the parameter is explicitly listed in an arbitrarily
-     * chosen <code>DataFlavor</code> which uses that MIME type. If so, the JRE
-     * will assume from that point on that the MIME type supports the charset
-     * parameter and will not check again. If the parameter is not explicitly
-     * listed, the JRE will assume from that point on that the MIME type does
-     * not support the charset parameter and will not check again. Because
-     * this check is performed on an arbitrarily chosen
-     * <code>DataFlavor</code>, developers must ensure that all
-     * <code>DataFlavor</code>s with a "text/&lt;other&gt;" MIME type specify
-     * the charset parameter if it is supported by that MIME type. Developers
-     * should never rely on the JRE to substitute the platform's default
-     * charset for a "text/&lt;other&gt;" DataFlavor. Failure to adhere to this
-     * restriction will lead to undefined behavior.
-     * <p>
-     * If the best MIME type in the array does not support the charset
-     * parameter, the flavors which share that MIME type will then be sorted by
-     * their representation classes in the following order:
-     * <code>java.io.InputStream</code>, <code>java.nio.ByteBuffer</code>,
-     * <code>[B</code>, &lt;all others&gt;.
-     * <p>
-     * If two or more flavors share the best representation class, or if no
-     * flavor has one of the three specified representations, then one of those
-     * flavors will be chosen non-deterministically.

-     * If the best MIME type in the array does support the charset parameter,

-     * representation classes in the following order:

-     * <code>java.nio.CharBuffer</code>, <code>[C</code>, &lt;all others&gt;.
-     * <p>
-     * If two or more flavors share the best representation class, and that
-     * representation is one of the four explicitly listed, then one of those
-     * flavors will be chosen non-deterministically. If, however, no flavor has
-     * one of the four specified representations, the flavors will then be
-     * sorted by their charsets. Unicode charsets, such as "UTF-16", "UTF-8",
-     * "UTF-16BE", "UTF-16LE", and their aliases, are considered best. After
-     * them, the platform default charset and its aliases are selected.
