/**
|
|
* @brief Sensitive detector.
|
|
*
|
|
* Describes how to store the energy deposited within the detector.
|
|
* It derives from two classes: G4VSensitiveDetector and
|
|
* G4VFastSimSensitiveDetector. Addition of G4VFastSimSensitiveDetector is
|
|
* necessary in order to handle the energy deposits from the fast simulation.
|
|
*
|
|
* Two ProcessHits() methods are introduced to handle energy deposited from full
|
|
* (detailed) simulation, and from fast simulation. The common part is handled
|
|
* by RetrieveAdnSetupHit() method.
