31 // An easy to use interface to the MUON module data stored in TreeK, TreeH, TreeS, TreeD and TreeR
32 // One can fetch any of the data objects with all the calls to runloader, muon loader and AliMUONData
33 // done behind the scenes and automatically.
34 // This interface in not necessarily the fastest way to fetch the data but it is the easiest.
35 // Note: If independant calls to the run loader, muon loader or AliMUONData objects are interspersed
36 // with calls to the AliMUONDataInterface to fetch data, one might need to call the Reset method
37 // between these method calls at some point to prevent AliMUONDataInterface from getting confused.
38 // This is necessary since this object assumes the state of runloader, muon loader nor AliMUONData
39 // has not changed between calls. If the state has changes then one must call Reset so that
40 // AliMUONDataInterface refreshes what it knows about the state of the loader and AliMUONData objects.
