Writing TObject object in ROOT file problem

ROOT
1

Hello.

I’m trying to write an event class having information in it.
Attached is the event class and two classes having hit and cluster information that will be contained in the event class.
I wrote a script for generating shared library ( test.sh )
and macro file for testing save process ( test.C )

After running two files, test.root file is generated.
Inside that, one class is stored correctly ( STHit in fHitArray ),
but the other is only partially stored ( STHitCluster in fClusterArray ).

I’m keep thinking about this for two days and still getting nothing.

Could you please give me some idea?

Thanks in advance.

Hi Genie,

Using exclamation marks in comments after class members prevent the streaming of those members. So simply replace:

    Int_t fClusterID;     //!< Cluster ID
    TVector3 fPosition;   //!< Cluster position
    TVector3 fPosSigma;   //!< Cluster position uncertainty
    TMatrixD fCovMatrix;  //!< Cluster covariance matrix
    Double_t fCharge;     //!< Cluster Charge
[/code]By:
[code]    //!< Cluster ID
    Int_t fClusterID;
    //!< Cluster position
    TVector3 fPosition;
    //!< Cluster position uncertainty
    TVector3 fPosSigma;
    //!< Cluster covariance matrix
    TMatrixD fCovMatrix;
    //!< Cluster Charge
    Double_t fCharge;

Or even better, just remove the exclamation marks… Int_t fClusterID; // Cluster ID TVector3 fPosition; // Cluster position TVector3 fPosSigma; // Cluster position uncertainty TMatrixD fCovMatrix; // Cluster covariance matrix Double_t fCharge; // Cluster Charge

Thank you so much, Bertrand.

Those are for doxygen so I couldn’t imagine those are the problem!
I changed them to another type.

Thank you Again!! :smiley:
