// Class AliEvent
// Creation and investigation of an Alice physics event.
-// An AliEvent can be constructed by adding AliTracks, Alivertices
-// and/or AliJets.
+// An AliEvent can be constructed by adding AliTracks, Alivertices, AliJets
+// and/or devices like AliCalorimeters or AliDevice (derived) objects.
+//
+// All objects which are derived from TObject can be regarded as a device.
+// However, AliDevice (or derived) objects profit from additional hit
+// handling facilities.
+// A "hit" is a generic name indicating an AliSignal (or derived) object.
+// Note that AliEvent does NOT own hits; it only provides references to hits
+// obtained from the various devices.
+// This implies that hits should be owned by the devices themselves.
//
// 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 devices like
+// AliCalorimeter objects, which can be selected by means of the memberfunction
+// SetDevCopy().
+//
+// 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.
+//
+// Note :
+// Modifications made to the original devices also affect the device
+// objects which are stored in the AliEvent.
+//
+// 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 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.
//
-// Coding example to make an event consisting of a primary vertex
-// and 2 secondary vertices.
+// 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.
+// Examples for this may be seen from AliCalorimeter, AliSignal and AliDevice.
+//
+// See also the documentation provided for the memberfunction SetOwner().
+//
+// Coding example to make an event consisting of a primary vertex,
+// 2 secondary vertices and a calorimeter.
