DigitContainers are sorted by DigitCollections which are the ensemble of all hits in a given MuonChamber.
To fill the final DigitContainer thread-safely, the DigitCollections shall be cached pre cached in a OutDigitCache_t vector which is later moved to the final DigitContainer

◆ digitize()

finaloverrideprotectedvirtual |
Digitize the time ordered hits and write them to the digit format specific for the detector technology.
A new MuonSimHitContainer pointer is parsed to also create the MuonSDO. If a new SDO should be added to the container plese use the addSDO() method as defined below.
Fetch the conditions for efficiency calculations
Standard digitization path
We need to rotate the local frame in order to be consistent with the Identifier
Write everything at the end into the final digit container
