+/**
+ * Encodes and decodes to and from Base64 notation.
+ *
+ * <p>
+ * Change Log:
+ * </p>
+ * <ul>
+ * <li>v2.1 - Cleaned up javadoc comments and unused variables and methods. Added
+ * some convenience methods for reading and writing to and from files.</li>
+ * <li>v2.0.2 - Now specifies UTF-8 encoding in places where the code fails on systems
+ * with other encodings (like EBCDIC).</li>
+ * <li>v2.0.1 - Fixed an error when decoding a single byte, that is, when the
+ * encoded data was a single byte.</li>
+ * <li>v2.0 - I got rid of methods that used booleans to set options.
+ * Now everything is more consolidated and cleaner. The code now detects
+ * when data that's being decoded is gzip-compressed and will decompress it
+ * automatically. Generally things are cleaner. You'll probably have to
+ * change some method calls that you were making to support the new
+ * options format (<tt>int</tt>s that you "OR" together).</li>
+ * <li>v1.5.1 - Fixed bug when decompressing and decoding to a
+ * byte[] using <tt>decode( String s, boolean gzipCompressed )</tt>.
+ * Added the ability to "suspend" encoding in the Output Stream so
+ * you can turn on and off the encoding if you need to embed base64
+ * data in an otherwise "normal" stream (like an XML file).</li>
+ * <li>v1.5 - Output stream pases on flush() command but doesn't do anything itself.
+ * This helps when using GZIP streams.
+ * Added the ability to GZip-compress objects before encoding them.</li>
+ * <li>v1.4 - Added helper methods to read/write files.</li>
+ * <li>v1.3.6 - Fixed OutputStream.flush() so that 'position' is reset.</li>
+ * <li>v1.3.5 - Added flag to turn on and off line breaks. Fixed bug in input stream
+ * where last buffer being read, if not completely full, was not returned.</li>
+ * <li>v1.3.4 - Fixed when "improperly padded stream" error was thrown at the wrong time.</li>
+ * <li>v1.3.3 - Fixed I/O streams which were totally messed up.</li>
+ * </ul>
+ *
+ * <p>
+ * I am placing this code in the Public Domain. Do with it as you will.
+ * This software comes with no guarantees or warranties but with
+ * plenty of well-wishing instead!
+ * Please visit <a href="http://iharder.net/base64">http://iharder.net/base64</a>

+ In any event, I hope with one or more of these Base64 tools, you won't

+ <strong>Changes:</strong>
+ <ul>
+<li>v2.1 - Cleaned up javadoc comments and unused variables and methods. Added
+ some convenience methods for reading and writing to and from files.</li>
+ <li>
+ v2.0.2 - Now specifies UTF-8 encoding in places where the code fails on systems
+ with other encodings (like EBCDIC).
+ </li>
+
+ <li>v2.0.1 - Fixed an error when decoding a single byte, that is, when the
+ encoded data was a single byte.</li>
+ <li>v2.0 - I got rid of methods that used booleans to set options.
+ Now everything is more consolidated and cleaner. The code now detects
+ when data that's being decoded is gzip-compressed and will decompress it
+ automatically. Generally things are cleaner. You'll probably have to
+ change some method calls that you were making to support the new
+ options format (<tt>int</tt>s that you "OR" together).</li>
+
+ <li>v1.5.1 - Fixed bug when decompressing and decoding to a
+ byte[] using <tt>decode( String s, boolean gzipCompressed )</tt>.
+ Added the ability to "suspend" encoding in the Output Stream so
+ you can turn on and off the encoding if you need to embed base64
+ data in an otherwise "normal" stream (like an XML file).
+ <em>This has not been fully tested, so please alert me to bugs.</em></li>
+ <li>v1.5 - Output stream pases on flush() command but doesn't do anything itself. This helps when using GZIP streams. Added the ability to <strong>GZip-compress objects</strong> before encoding them.</li>
+ <li>v1.4 - Added some helper methods for reading and writing to/from files.</li>
+ <li>v1.3.6 - Fixed OutputStream.flush() so that 'position' is reset.</li>
+ <li>v1.3.5 - Added flag to turn on and off line breaks. Fixed bug in input stream
+ where last buffer being read, if not completely full, was not returned.</li>
+ <li>v1.3.4 - Fixed when <em>Improperly padded base64 stream</em> exception
+ was incorrectly thrown.</li>
+ <li>A bug has been fixed that kept I/O streams from working at all, really.</li>
+ <li>A bug has been fixed affecting you if you use the Base64.InputStream
+ to encode data.
+ </li>
+ <li>A bug has been fixed where if you specified an offset when encoding
+ an array of bytes, the offset was ignored.
+ </li>
+ </ul>
+ </p>

+ <p>
+ The easiest way to convert some data is with the convenience methods:
+ </p>
+<code><pre>String result1 = <strong>Base64.encodeObject</strong>( mySerializableObject );
+String result2 = <strong>Base64.encodeBytes</strong>( new byte[]{ 3, 34, 116, 9 } );
+</pre></code>
+
+ <p>
+ Or you can use the very efficient streams:
+ </p>
+<code><pre>OutputStream out = <strong>new Base64.OutputStream</strong>(
+ new FileOutputStream( "out.txt" ) );
+// Go on about your outputting...
+// ...
+
+InputStream in = <strong>new Base64.InputStream</strong>(
+ new FileInputStream( "in.txt" ) );
+// Go on about your inputting...
+// ...
+</pre></code>
+
+
+ <p>
+ There are defaults (OutputStream encodes, InputStream decodes),
+ but you can easily override that:
+ </p>
+<code><pre>OutputStream out = new Base64.OutputStream(
+ new FileOutputStream( "out.txt" ), <strong>Base64.DECODE</strong> );
+// Go on about your outputting...
+// ...
+</pre></code>
