Examples of java.io.ByteArrayOutputStream.reset()

java.io.ByteArrayOutputStream.reset()
Reset this ByteArrayOutputStream to the beginning of the underlying byte array. All subsequent writes will overwrite any bytes previously stored in this stream.

                    break;
                default:
                    if (seenCR) {
                        seenCR = false; // swallow final CR
                        listener.handle(new String(lineBuf.toByteArray(), cset));
                        lineBuf.reset();
                        rePos = pos + i + 1;
                    }
                    lineBuf.write(ch);
                }
            }
