This class provides a way of seamlessly concatenating the data from two or more input streams. It provides an InputStream interface to a sequence of InputStream objects. Data is read from the streams in the order in which the streams are specified. When the end of one stream is reached, data is automatically read from the next stream. This class might be useful, for example, when implementing an include file facility for a parser.
