Hello,
I'm facing a small problem concerning the TClonesArray constructor :
I create a TClonesArray with the usual constructor :
TClonesArray* aclone = new TClonesArray("aclassname",100) ;
If the classname is not known by ROOT (i.e gROOT->GetClass("classname")
fails) one gets the message : "classname is not a valid clas name"
and MakeZombie() is called .
Since I want to test if the TClonesArray has been successfuly built , that
means not only have a message but be able to stop my prog somehow I
decided to test the TClonesArray by : aclone->IsZombie() but this doesn't
work, so to sum up the code :
TClonesArray* trackarray = 0 ;
TClonesArray* muonarray = 0;
....
trackarray = InitArrays(track_branch,trackarray,"Track") ;
muonarray = Init...
TClonesArray* InitArrays(TBranchElement* abranch,
TClonesArray* aclonesarray,
TString aclassname)
{
if(abranch) {
aclonesarray = new TClonesArray(aclassname.Data(),100) ;
if(aclone->IsZombie()) return 0 ;
else {
tree->SetBranchAddress(abranch->GetName(),&aclonesarray);
return aclonesarray ;
}
}
else {
cout << "couldn't find branch" << endl ;
return 0 ;
}
}
Am I doing something wrong ?
Thanks for help,
seb.
ps : by the way the second constructor of TClonesArray :
TClonesArray(const TClass *cl,....)
does not have the call MakeZombie() if cl is NULL, just a message error
