// Class description:
|
|
//
|
|
// A physics vector which has values of energy-loss, cross-section,
|
|
// and other physics values of a particle in matter in a given
|
|
// range of the energy, momentum, etc.
|
|
// This class serves as the base class for a vector having various
|
|
// energy scale, for example like 'log', 'linear', 'free', etc.
|
|
|
|
// History:
|
|
// 02 Dec. 1995, G.Cosmo : Structure created based on object model
|
|
// 03 Mar. 1996, K.Amako : Implemented the 1st version
|
|
// 27 Apr. 1996, K.Amako : Cache mechanism added
|
|
// 01 Jul. 1996, K.Amako : Now GetValue not virtual.
|
|
// 21 Sep. 1996, K.Amako : Added [] and () operators.
