Unified I/O is high performance Java I/O library. It features high performance (due to buffering), memory management, the ability to access streams, arrays, and files using the same interface, the ability to read or write directly from or into primitive arrays, and optimized reading over HTTP. Unified I/O also contains many utilities: Transformer, BitInputStream and BitOutputStream, PackBits, a RLE4 and RLE8 decoder, a base64 codec implementation, and many others. License: BSD License (revised) Changes: Creating independent child streams has been added. The ability to synchronize access to stream content has been added. The user can specify the directory to be used for creating temporary files. If such a directory is specified, UIO will always use File Caching for InputStream and URL (File Caching for OutputStream will be added later). XTransformer has been added: it is the same as Transformer, but does not restricted you to big/little endiannes, i.e. it can read bytes in any user-specified order. A bug has been fixed where BufferPosition moved from buffer to stream.
