◆ RegisterOutput()

void CbmDigitize< CbmRichDigi >::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.

Definition at line 189 of file CbmDigitize.h.

Referenced by Init().

◆ SendData()

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

inlineinherited

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

Parameters

time	Global time of the digi
digi	Pointer to digi object (template parameter)
match	Pointer 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.
