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. |
