|

|
---|
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 function of the tasks are
|
---|
41 | // executed as long as one function returns kSTOP. Only the tasks which
|
---|
42 | // are marked as "All" or with a string which matches the MInputStreamID
|
---|
43 | // of 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 | // If you want to display the progress in a gui you can use SetProgressBar
|
---|
49 | // and a TGProgressBar or a MProgressBar. If you set a MStatusDisplay
|
---|
50 | // using SetDisplay, the Progress bar from this display is used.
|
---|
51 | //
|
---|
52 | // You can create a macro from a completely setup eventloop by:
|
---|
53 | // evtloop.MakeMacro("mymacro.C");
|
---|
54 | //
|
---|
55 | // You will always need to check the macro, it will not run, but it
|
---|
56 | // should have al important information.
|
---|
57 | //
|
---|
58 | //
|
---|
59 | // You can also write all this information to a root file:
|
---|
60 | // TFile file("myfile.root");
|
---|
61 | // evtloop.Write("MyEvtloopKey");
|
---|
62 | //
|
---|
63 | // You can afterwards read the information from an open file by:
|
---|
64 | // evtloop.Read("MyEvtloopKey");
|
---|
65 | //
|
---|
66 | // To lookup the information write it to a file using MakeMacro
