29 // Language: C++
30 // Tested on: g++
31 // Prerequisites: None
32 // Purpose: This is the place, where all the materials get defined.
33 // Instead of coding those materials locally, where they
34 // are needed, it is much easier to maintain, if we keep
35 // all materials for a detector component in one place.
36 // Everybody who needs some of these parameters, can
37 // query the FCALMaterialConsultant.
38 // --> This class is made a singleton by making the
39 // constructor private and hiding it behind the
40 // construct() method, which creates a first instance
41 // if it does not exist. This is to prevent multiple
42 // copies of this consultant with potentially different
43 // contents (once the data is loaded from files and/or
44 // can be changed by user interaction).
45 // --> The method Material is provided to access to the data
46 // stored, a routine ShowMeAllYouKnow can be queried to
47 // dump the entire knowledge of this consultant.
48 //
49 // * Ideas on how the theFCALMaterialConsultant pointer
50 // is made static are borrowed from G4VisManager.
