All Implemented Interfaces:

Closeable

public class InputStreamCombiner
extends InputStream

An input stream implementation that reads one or more input streams sequentially. When the end of the first stream has been reached, reading continues on the next one, and so on until all streams have been read. The underlying streams are automatically closed once they have been fully read.
