Examples of java.io.BufferedInputStream.reset()

java.io.BufferedInputStream.reset()
See the general contract of the reset method of InputStream.
If markpos is -1 (no mark has been set or the mark has been invalidated), an IOException is thrown. Otherwise, pos is set equal to markpos. @exception IOException if this stream has not been marked or,if the mark has been invalidated, or the stream has been closed by invoking its {@link #close()}method, or an I/O error occurs. @see java.io.BufferedInputStream#mark(int)
