std::vector<std::string>*

In recent verions of fermi/glast n-tuples a string variable has been added of the form:

vector<string>* Source_Name

I had some instructions for dealing with tup->Draw("var","cut"). These work, and I can, e.g., compare |Source_Name| to a |TString| in the cut.

However, when I try to the same thing in a selector (made with |tup->MakeSelector| it fails to compile.

Code fragment is:

   if(agnTimeGap::agnName!="") {

     cout << "name:" << agnName << endl;
     //    cout << "source:" << *Source_Name << endl;
     if(agnTimeGap::agnName!=Source_Name) return kTRUE;
     cout << "got it" << endl;

which is like the 'code' as it appears in |Draw|.

The error message is

/afs/slac.stanford.edu/u/ek/snyder/glast/root/./agnTimeGap.cc:95: error:
invalid conversion from `std::vector<std::string, std::allocator<std::string> >*' to `char'
/afs/slac.stanford.edu/u/ek/snyder/glast/root/./agnTimeGap.cc:95: error:
initializing argument 1 of `TString::TString(char)'

Putting a * in front of |Source_Name| produces a different error.

So how am I supposed to compare at |TString| to a |vector<string>*|?
