Dear all -
Thank you for your past help… as I progress, I get stuck on the next complexity level
- Problem.
I would like to record the following structure:
- I have TMyEvent class that holds TCloneArrays of another class, TMySample
- Each TMySample holds a certain number of TMyAxis objects, also as TClonesArray (suggestions welcome)
- each of the TMyAxis holds some data, such as arrays of floats
So my goal is to have:
TMyEvent (nevent, nsample, TClonesArray *fSamples)
|____ TMySample (sampleid, naxis, TClonesArray *fAxes)
|____TMyAxis (axisid, nchannels, chdata [nchannels] )
You have helped me with the TMyAxis (axisid, nchannels, chdata [nchannels] ) portion and it works.
But now I just tried to do “monkey see / monkey do” approach and extend this to one more nested level with classes… and failing to do so.
I attach the example and the classes definition and the nestedclass.C
It creates the shared object but crashes when I try to add the first TMySample.
Please help me to make such storage structure.
I am not hell-bent on this solution, so if there is a different and more elegant way to achieve the nested structure, I would welcome all suggestions!
I could think this is something common (Event has Jets, each Jet has Tracks, track has particles in them…) I just did not find a good example that would define such structure.
Thank you, best -
Evgeny.
