In the "higher level" methods such as + * encodeBytes( bytes, options ) the options parameter can be used to indicate such + * things as first gzipping the bytes before encoding them, not inserting linefeeds + * (though that breaks strict Base64 compatibility), and encoding using the URL-safe + * and Ordered dialects.</p> + * + * <p>The constants defined in Base64 can be OR-ed together to combine options, so you + * might make a call like this:</p> + * + * <code>String encoded = Base64.encodeBytes( mybytes, Base64.GZIP | Base64.DONT_BREAK_LINES );</code> + * + * <p>to compress the data before encoding it and then making the output have no newline characters.</p> + * + * + * <p> + * Change Log: + * </p> + * <ul> + * <li>v2.2.2 - Fixed encodeFileToFile and decodeFileToFile to use the + * Base64.InputStream class to encode and decode on the fly which uses + * less memory than encoding/decoding an entire file into memory before writing.</li> + * <li>v2.2.1 - Fixed bug using URL_SAFE and ORDERED encodings. Fixed bug + * when using very small files (~< 40 bytes).</li> + * <li>v2.2 - Added some helper methods for encoding/decoding directly from + * one file to the next. Also added a main() method to support command line + * encoding/decoding from one file to the next. Also added these Base64 dialects: + * <ol> + * <li>The default is RFC3548 format.</li> + * <li>Calling Base64.setFormat(Base64.BASE64_FORMAT.URLSAFE_FORMAT) generates + * URL and file name friendly format as described in Section 4 of RFC3548. + * http://www.faqs.org/rfcs/rfc3548.html</li> + * <li>Calling Base64.setFormat(Base64.BASE64_FORMAT.ORDERED_FORMAT) generates + * URL and file name friendly format that preserves lexical ordering as described + * in http://www.faqs.org/qa/rfcc-1940.html</li> + * </ol> + * Special thanks to Jim Kellerman at <a href="http://www.powerset.com/">http://www.powerset.com/</a> + * for contributing the new Base64 dialects. + * </li> + * + * <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.
