Hello,
I am writing a rootinterface for a MC Generator. I wrote my on
eventclass, verticesclass and particleclass all inheriting from TObject.
Now in the interface i make a tree and give a Branch the events address.
in This eventbrach i want to have a TClonesArray of my vertexobjects.
I built the dictionary and it worked so that the event and the vertex
class have their own streamer.
I tested the TClonesarray in the code so that i now know that filling
the TClonesArray workes(I can readout vertex members after filling the
array).
I think the problem is when the event streamer calls the
'TClonesArrayobject'->Streamer(b) and there the Vertex Streamer is not
called. Because i only see the events members as leafes and one leaf
with the name of the TClonesArray. Normaly it should be browsable
because i split the tree (with 99). I now do not see why the
TClonesArray with my Vertex Objects are not streamed in the file and it
is not browsable...
Code:
void HepMCEvent::Streamer(TBuffer &R__b) {
// Stream an object of class HepMCEvent.
UInt_t R__s, R__c;
if (R__b.IsReading()) {
Version_t R__v = R__b.ReadVersion(&R__s, &R__c); if (R__v) { }
TObject::Streamer(R__b);
R__b >> signal_process_id;
R__b >> event_number;
R__b >> event_scale;
R__b >> alphaQCD;
R__b >> alphaQED;
R__b >> vertices_size;
Vertices->Streamer(R__b);
R__b.CheckByteCount(R__s, R__c, HepMCEvent::IsA());
} else {
R__c = R__b.WriteVersion(HepMCEvent::IsA(), kTRUE);
TObject::Streamer(R__b);
R__b << signal_process_id;
R__b << event_number;
R__b << event_scale;
R__b << alphaQCD;
R__b << alphaQED;
R__b << vertices_size;
Vertices->Streamer(R__b);
R__b.SetByteCount(R__c, kTRUE);
// Stream an object of class HepMCVertex.
UInt_t R__s, R__c;
if (R__b.IsReading()) {
Version_t R__v = R__b.ReadVersion(&R__s, &R__c); if (R__v) { }
TObject::Streamer(R__b);
R__b >> barcode;
R__b >> id;
R__b >> position_x;
R__b >> position_y;
R__b >> position_z;
R__b >> position_t;
R__b >> numOrphan;
R__b >> particles_out_size;
R__b.CheckByteCount(R__s, R__c, HepMCVertex::IsA());
} else {
R__c = R__b.WriteVersion(HepMCVertex::IsA(), kTRUE);
TObject::Streamer(R__b);
R__b << barcode;
R__b << id;
R__b << position_x;
R__b << position_y;
R__b << position_z;
R__b << position_t;
R__b << numOrphan;
R__b << particles_out_size;
R__b.SetByteCount(R__c, kTRUE);
