EMA C++ can not pass a OmmArray to OmmConsumerClient

I create a class who inherited the OmmConsumerClient, and I pass a OmmArray to the construction function in order to decode the fids that I want

RefinitivClient::RefinitivClient(const OmmArray & fids)

: m_fids(fids)

{

}

void RefinitivClient::decode(const refinitiv::ema::access::FieldList & fl)

{

ElementList search;

search.addArray("test", m_fids.complete()).complete();

}

It will charge all of the fids

I have tested it with the Cons120 example in the RTSDK-2.0.1.L2.win.rrg package. The main function contains the following code.


OmmArray fidArray;
        fidArray.fixedWidth(2).addInt(22).addInt(25).addInt(30).addInt(31).addInt(3);
        
        AppClient client(fidArray);
        OmmConsumer consumer(OmmConsumerConfig().host("localhost:14002").username("user"));
            
        consumer.registerClient( ReqMsg().serviceName( "ELEKTRON_DD" ).name( "JPY=" ), client );

The decode function contains the following code.

void AppClient::decode( const FieldList& fl )
{
    ElementList search;


    search.addArray("test", m_fids.complete()).complete();
    while (fl.forth(search))    {
        const FieldEntry& fe = fl.getEntry();
        cout << "Filter Fid: " << fl.getEntry().getFieldId() << " Name: " << fl.getEntry().getName() << " value: " << fl.getEntry().getLoad().toString() << endl;
    } 
}

The output contains the required fields.

Hi @he.wu,

I'm not clear on what issues you are facing or what you are trying to do. Within your decode, you typically walk through the fieldList that is passed and pull out the data. Within your code segment, you don't appear to be processing the incoming fieldList, but instead creating an ElementList. Can you provide more detail?

hi @nick.zincone12

tks for your return, in fact, I pass a OmmArray which contains all the fids that I need for the construction of OmmConsumerClient.

And then, when I receive the notif of refinitiv, I will decode it, but I can not filter the notif by the OmmArray

void RefinitivClient::decode(const FieldList& fl)

{

ElementList search;

search.addArray("test", m_fids.complete()).complete();

while (fl.forth(search))

{

const FieldEntry& fe = fl.getEntry();

cout << "Name: " << fe.getName() << " Value: ";

}

in my code, normally, it will only deocde the fids contains in OmmArray, but it still decode all of fids

@Jirapongse

excuse me, could you give me your constructor function of your AppCLient ?
