* Reads simulated digis from a root file and samples the digi as a time-series UDP stream.
|
|
* Must be initialized with the filename to the root file and the name of the sub-detector
|
|
* branch, whose digis should be streamed.
|
|
*
|
|
* The purpose of this class is to provide a data source of digis very similar to the
|
|
* future detector output at the point where the detector is connected to the online
|
|
* computing farm. For the development of online analysis algorithms, it is very important
|
|
* to simulate the future detector output as realistic as possible to evaluate the
|
|
* feasibility and quality of the various possible online analysis features.
