Detailed Description

Example of TTasks.

Create a hierarchy of objects derived from TTask in library Mytasks Show the tasks in a browser. To execute a Task, use the context context menu and select the item "ExecuteTask" see also other functions in the TTask context menu, such as

#ifndef __RUN_TASKS__
void tasks()
{
TString dir = gSystem->UnixPathName(__FILE__);
dir.ReplaceAll("tasks.C","");
dir.ReplaceAll("/./","/");
gROOT->LoadMacro(dir +"MyTasks.cxx+");
gROOT->ProcessLine("#define __RUN_TASKS__ 1");
gROOT->ProcessLine(TString("#include \"") + dir + "tasks.C\"");
gROOT->ProcessLine("runtasks()");
gROOT->ProcessLine("#undef __RUN_TASKS__");
}
#else
void runtasks()
//void tasks()
{
TTask *run = new MyRun("run","Process one run");
TTask *event = new MyEvent("event","Process one event");
TTask *geomInit = new MyGeomInit("geomInit","Geometry Initialisation");
TTask *matInit = new MyMaterialInit("matInit","Materials Initialisation");
TTask *tracker = new MyTracker("tracker","Tracker manager");
TTask *tpc = new MyRecTPC("tpc","TPC Reconstruction");
TTask *its = new MyRecITS("its","ITS Reconstruction");
TTask *muon = new MyRecMUON("muon","MUON Reconstruction");
TTask *phos = new MyRecPHOS("phos","PHOS Reconstruction");
TTask *rich = new MyRecRICH("rich","RICH Reconstruction");
TTask *trd = new MyRecTRD("trd","TRD Reconstruction");
TTask *global = new MyRecGlobal("global","Global Reconstruction");
run->Add(geomInit);
