Chain processing in Ema C/C++

vladislav.tolmachyov

Hello,

I could not find any LSEG 64Bit C/C++ examples of how to process chains in Ema.

Can somebody please point me to the one?

Thanks, Vlad.

Hi @vladislav.tolmachyov,

There are two part articles which explain Chain processing in EMA. The accompanying code is in EMA Java, but same concept will apply to C++ as well.

I got the article and am familiar with concepts. For Java a chain processing is based on ValueAddObjectsForEma library. Does similar library exist for C/C++ with chains implementation in it?

Hi @vladislav.tolmachyov​,

No we don't have a similar library for C++. The closest is the sample in .NET C#.

Ok, is there C++ Refinitiv/LSEG provided API? Where is it documented?

No, there is no C++ API or library for Chains processing.

So, if I have old C++ 32Bit application that uses chains and I need to convert it to new 64Bit EMA application what are my choices?

Hi @vladislav.tolmachyov,

Which API does your existing 32 bit application use? Essentially the chain processing logic is same - regardless of the API or language, and this processing logic is described in detail in the two part articles shared in previous answer.
