org.javarosa.core.util.MultiInputStream

All Implemented Interfaces:

Closeable, AutoCloseable

public class MultiInputStream
extends InputStream

MultiInputStream allows for concatenating multiple input streams together to be read serially in the order that they were added. A MultiInputStream must have all of its component streams added to it before it can be read from. Once the stream is ready, it should be prepare()d before the first read.
