// Class description:
|
|
//
|
|
// An implementation of an "importance store" with the interface
|
|
// G4VIStore. See description in G4VIStore.
|
|
// This implementation uses G4GeometryCellImportance as the container
|
|
// to store the "cells" together with the importance values.
|
|
// Giving a cell the importance 0 is allowed as a flagging that no biasing
|
|
// should happen between this cell and its neighbors.
|
|
// If a cell is not known by the importance store no biasing should be
|
|
// applied between this cell and its nighbors.
