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