|
|---|
| 29 | // //
|
|---|
| 30 | // This class is the core of each event processing. //
|
|---|
| 31 | // First you must set the parameter list to use. The parameter list //
|
|---|
| 32 | // must contain the task list (MTaskList) to use. The name of the task //
|
|---|
| 33 | // list can be specified if you call Eventloop. The standard name is //
|
|---|
| 34 | // "MTaskList". The name you specify must match the name of the MTaskList //
|
|---|
| 35 | // object. //
|
|---|
| 36 | // //
|
|---|
| 37 | // If you call Eventloop first all PreProcess functions - with the //
|
|---|
| 38 | // parameter list as an argument - of the tasks in the task list are //
|
|---|
| 39 | // executed. If one of them returns kFALSE then the execution is stopped. //
|
|---|
| 40 | // If the preprocessing was ok. The Process funtion of the tasks are //
|
|---|
| 41 | // as long as one function returns kSTOP. Only the tasks which are marked //
|
|---|
| 42 | // marked as "All" or with a string which matches the MInputStreamID of //
|
|---|
| 43 | // MTaskList are executed. If one tasks returns kCONTINUE the pending //
|
|---|
| 44 | // tasks in the list are skipped and the execution in continued with //
|
|---|
| 45 | // the first one in the list. //
|
|---|
| 46 | // Afterwards the PostProcess functions are executed. //
|
|---|
| 47 | // //
|
|---|
| 48 | // //
|
|---|
| 49 | // Maybe we can add a TProgressMeter sometimes later to be able to show //
|
|---|
| 50 | // the progress graphically... //
|
|---|
| 51 | // //
|
|---|
| 52 | // //
|
|---|
| 53 | // You can create a macro from a completely setup eventloop by: //
|
|---|
| 54 | // evtloop.MakeMacro("mymacro.C"); //
|
|---|
| 55 | // //
|
|---|
| 56 | // You will always need to check the macro, it will not run, but it //
|
|---|
| 57 | // should have al important information. //
|
|---|
| 58 | // //
|
|---|
| 59 | // //
|
|---|
| 60 | // You can also write all this information to a root file: //
|
|---|
| 61 | // TFile file("myfile.root"); //
|
|---|
| 62 | // evtloop.Write("MyEvtloopKey"); //
|
|---|
| 63 | // //
|
|---|
| 64 | // You can afterwards read the information from an open file by: //
|
|---|
| 65 | // evtloop.Read("MyEvtloopKey"); //
|
|---|
| 66 | // //
|
|---|
| 67 | // To lookup the information write it to a file using MakeMacro //
|
