// G4GeometryWorkspace
|
|
//
|
|
// Class Description:
|
|
//
|
|
// Class managing the per-thread state of the geometry, spanning those
|
|
// which have a per-thread state and their dependents.
|
|
// In particular it:
|
|
// - owns the arrays that implement 'split' classes
|
|
// - owns classes/objects which are owned by the split classes.
|
|
// The classes/objects affected are:
|
|
// - 'split' classes part of its state is per-thread,
|
|
// - per-thread objects, in particular those which are owned
|
|
// by the split classes.
|
|
// Goal: Take ownership and control of per-thread state of
|
|
// classes to work with multi-threading.
