Get event information.

MC input number, entry number and event time are taken from FairEventHeader and stored in the private data members for convenience.

◆ RegisterOutput()

void CbmDigitize< CbmPsdDigi >::RegisterOutput ( )
inlineinherited

Register the output arrays.

Arrays for the digis and the match objects will be created and registered as output to the ROOT tree. The current implementation uses std::vector as container.

Referenced by Init().

◆ SendData()

void CbmDigitize< CbmPsdDigi >::SendData ( Double_t time,
CbmPsdDigi * digi,
CbmMatch * match = nullptr )
inlineinherited

Send a digi and the corresponding match object to the DAQ.

Parameters
timeGlobal time of the digi
digiPointer to digi object (template parameter)
matchPointer to match object

Time is passed as a seperate parameter because the global time might be too large for some digi classes to store internally. So digis are not required to have a valid timestamp at this point. Later on when the time slices are known, the timestamp is overwritten with the relative time to the beginning of the time slice.

TODO: The interface should be unique pointers, meaning that the digitisers have to create objects by unique pointers from the start.
