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)

  public void test_reset_Exception() throws IOException {
    BufferedInputStream bis = new BufferedInputStream(null);
    
    //throws IOExcepiton with message "Mark has been invalidated"
    try {
      bis.reset();
      fail("should throw IOException");
    } catch (IOException e) {
      // expected
    }
