Receiving Long Message #92

Open GoogleCodeExporter opened 8 years ago

Hi,

I am facing an issue in interpreting the optional parameters when receiving 
long message.

Is there any sample code which displays how to read optional parameters?

Hi !

This is what i'm currently using :

    public static byte [] newPayLoad(OptionalParameter [] parameters) {
        byte [] result = null;
        for (OptionalParameter param : parameters) {
            if (param.tag ==Tag.MESSAGE_PAYLOAD.code()) {
                result = getValue(param);
                break;
            }
        }
        return result;
    }

    private static byte[] getValue(OptionalParameter param) {
        byte [] value = param.serialize();
        byte [] result = new byte[value.length -4];
        System.arraycopy(value, 4, result, 0, value.length-4);
        return result;
    }

Take care that not all the optional parameters are treated the same :

    public static int newSarMsgRefNum(OptionalParameter [] parameters) {
        int result = 0;
        for (OptionalParameter param : parameters) {
            if (param.tag ==Tag.SAR_MSG_REF_NUM.code()) {
                byte [] serialize = param.serialize();
                result = OctetUtil.bytesToShort(serialize,4);
                break;
            }
        }
        return result;
    }

or 
    public static int newSarSegmentSeqnum(OptionalParameter [] parameters) {
        int result = 0;
        for (OptionalParameter param : parameters) {
            if (param.tag == Tag.SAR_SEGMENT_SEQNUM.code()) {
                byte [] serialize = param.serialize();
                result = serialize[4];
                break;
            }
        }
        return result;
    }

Probably there's a better way, but that's the way it's working for me.
