|
// Class description:
|
|
//
|
|
// Base class for parameterisations that use information from the parent
|
|
// volume to compute the material of a copy/instance of this volume.
|
|
// This is in addition to using the current replication number.
|
|
//
|
|
// Notes:
|
|
// - Such a volume can be nested inside a placement volume or a parameterised
|
|
// volume.
|
|
// - The user can modify the solid type, size or transformation using only
|
|
// the replication number of this parameterised volume.
|
|
// He/she is NOT allowed to change these attributes using information of
|
|
// parent volumes - otherwise incorrect results will occur.
|
|
// Also note that the usual restrictions apply:
|
|
// - the mother volume, in which these copies are placed, must always be
|
|
// of the same dimensions
|
|
|
|
// History:
|
|
// 24.02.05 - J.Apostolakis - First created version.
