// Class AliEvent
// Creation and investigation of an Alice physics event.
// An AliEvent can be constructed by adding AliTracks, Alivertices, AliJets
-// and/or AliCalorimeters.
+// and/or devices like AliCalorimeters.
+// All objects which are derived from TObject can be regarded as a device.
//
// The basic functionality of AliEvent is identical to the one of AliVertex.
-// So, an AliEvent may be regarded as the primary vertex with some
-// additional functionality compared to AliVertex.
+// So, an AliEvent may be used as the primary vertex with some additional
+// functionality compared to AliVertex.
//
// To provide maximal flexibility to the user, the two modes of track/jet/vertex
// storage as described in AliJet and AliVertex can be used.
-// In addition an identical structure is provided for the storage of AliCalorimeter
-// objects, which can be selected by means of the memberfunction SetCalCopy().
+// In addition an identical structure is provided for the storage of devices like
+// AliCalorimeter objects, which can be selected by means of the memberfunction
+// SetDevCopy().
//
-// a) SetCalCopy(0) (which is the default).
-// Only the pointers of the 'added' calorimeters are stored.
-// This mode is typically used by making cal. studies based on a fixed set
-// of calorimeters which stays under user control or is kept on an external
+// a) SetDevCopy(0) (which is the default).
+// Only the pointers of the 'added' devices are stored.
+// This mode is typically used by making studies based on a fixed set
+// of devices which stays under user control or is kept on an external
// file/tree.
// In this way the AliEvent just represents a 'logical structure' for the
// physics analysis.
-// Modifications made to the original calorimeters also affect the AliCalorimeter
+//
+// Note :
+// Modifications made to the original devices also affect the device
// objects which are stored in the AliEvent.
-// b) SetCalCopy(1).
-// Of every 'added' calorimeter a private copy will be made of which the pointer
+//
+// b) SetDevCopy(1).
+// Of every 'added' device a private copy will be made of which the pointer
// will be stored.
// In this way the AliEvent represents an entity on its own and modifications
// made to the original calorimeters do not affect the AliCalorimeter objects
// which are stored in the AliEvent.
-// This mode will allow 'adding' many different AliCalorimeters into an AliEvent by
-// creating only one AliCalorimeter instance in the main programme and using the
-// AliCalorimeter::Reset() and AliCalorimeter parameter setting memberfunctions.
+// This mode will allow 'adding' many different devices into an AliEvent by
+// creating only one device instance in the main programme and using the
+// Reset() and parameter setting memberfunctions of the object representing the device.
+//
+// Note :
+// The copy is made using the Clone() memberfunction.
+// All devices (i.e. classes derived from TObject) have the default TObject::Clone()
+// memberfunction.
+// However, devices generally contain an internal (signal) data structure
+// which may include pointers to other objects. Therefore it is recommended to provide
+// for all devices a specific copy constructor and override the default Clone()
+// memberfunction using this copy constructor.
+// An example for this may be seen from AliCalorimeter.
+//
+// See also the documentation provided for the memberfunction SetOwner().
