SelectMany #38

Closed rohanaceres closed 4 years ago

rohanaceres commented 4 years ago

Hi,

How can I selectMany with objects? For example:

auto concatInnerList =
    from(*myObj)
        .selectMany([](const MyObj& myObjTemp) { return myObjTemp.innerList; })
        .toStdArray();

myObj is a std::vector<MyObject> which contains an inner list object std::vector.

Hi @rohanaceres, try return from(myObjTemp.innerList);
