-/**
- * General IO stream manipulation utilities.
- * <p>
- * This class provides static utility methods for input/output operations.
- * <ul>
- * <li>closeQuietly - these methods close a stream ignoring nulls and exceptions
- * <li>toXxx/read - these methods read data from a stream
- * <li>write - these methods write data to a stream
- * <li>copy - these methods copy all the data from one stream to another
- * <li>contentEquals - these methods compare the content of two streams
- * </ul>
- * <p>
- * The byte-to-char methods and char-to-byte methods involve a conversion step.
- * Two methods are provided in each case, one that uses the platform default
- * encoding and the other which allows you to specify an encoding. You are
- * encouraged to always specify an encoding because relying on the platform
- * default can lead to unexpected results, for example when moving from
- * development to production.
- * <p>
- * All the methods in this class that read a stream are buffered internally.
- * This means that there is no cause to use a <code>BufferedInputStream</code>
- * or <code>BufferedReader</code>. The default buffer size of 4K has been shown
- * to be efficient in tests.
- * <p>
- * Wherever possible, the methods in this class do <em>not</em> flush or close
- * the stream. This is to avoid making non-portable assumptions about the
- * streams' origin and further use. Thus the caller is still responsible for
- * closing streams after use.
- * <p>
- * Origin of code: Excalibur.

-/**
- * <p>
- * Receives notifications of the content of a plain RFC822 or MIME message.
- * Implement this interface and register an instance of that implementation
- * with a <code>MimeStreamParser</code> instance using its
- * {@link org.apache.james.mime4j.MimeStreamParser#setContentHandler(ContentHandler)}
- * method. The parser uses the <code>ContentHandler</code> instance to report
- * basic message-related events like the start and end of the body of a
- * part in a multipart MIME entity.
- * </p>
- * <p>
- * Events will be generated in the order the corresponding elements occur in
- * the message stream parsed by the parser. E.g.:
- * <pre>
- *      startMessage()
- *          startHeader()
- *              field(...)
- *              field(...)
- *              ...
- *          endHeader()
- *          startMultipart()
- *              preamble(...)
- *              startBodyPart()
- *                  startHeader()
- *                      field(...)
- *                      field(...)
- *                      ...
- *                  endHeader()
- *                  body()
- *              endBodyPart()
- *              startBodyPart()
- *                  startHeader()
- *                      field(...)
- *                      field(...)
- *                      ...
- *                  endHeader()
- *                  body()
- *              endBodyPart()
- *              epilogue(...)
- *          endMultipart()
- *      endMessage()
- * </pre>
- * The above shows an example of a MIME message consisting of a multipart
- * body containing two body parts.
- * </p>
- * <p>
- * See MIME RFCs 2045-2049 for more information on the structure of MIME

-/**
- * UnboundedFifoByteBuffer is a very efficient buffer implementation.
- * According to performance testing, it exhibits a constant access time, but it
- * also outperforms ArrayList when used for the same purpose.
- * <p>
- * The removal order of an <code>UnboundedFifoByteBuffer</code> is based on the insertion
- * order; elements are removed in the same order in which they were added.
- * The iteration order is the same as the removal order.
- * <p>
- * The {@link #remove()} and {@link #get()} operations perform in constant time.
- * The {@link #add(Object)} operation performs in amortized constant time.  All
- * other operations perform in linear time or worse.
- * <p>
- * Note that this implementation is not synchronized.  The following can be
- * used to provide synchronized access to your <code>UnboundedFifoByteBuffer</code>:
- * <pre>
- *   Buffer fifo = BufferUtils.synchronizedBuffer(new UnboundedFifoByteBuffer());
- * </pre>
- * <p>
- * This buffer prevents null objects from being added.

-/**
- * Utility class for working with character sets. It is somewhat similar to
- * the Java 1.4 <code>java.nio.charset.Charset</code> class but knows many
- * more aliases and is compatible with Java 1.3. It will use a simple detection
- * mechanism to detect what character sets the current VM supports. This will
- * be a sub-set of the character sets listed in the
- * <a href="http://java.sun.com/j2se/1.5.0/docs/guide/intl/encoding.doc.html">
- * Java 1.5 (J2SE5.0) Supported Encodings</a> document.
- * <p>
- * The <a href="http://www.iana.org/assignments/character-sets">
- * IANA Character Sets</a> document has been used to determine the preferred
- * MIME character set names and to get a list of known aliases.
- * <p>
- * This is a complete list of the character sets known to this class:
