28 | // MEvtLoop //
|

|
---|
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 //
