Detailed Description

A replacement for ByteArrayInputStream that does not synchronize every byte read.

This class extends InputStream and its read() methods allow it to be used as a standard input stream. In addition, it provides readFast() methods that are not declared to throw IOException. IOException is never thrown by this class.
