| 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.
