// File name: G4CrossSectionDataStore

|
|
// Modifications:
|
|
// 23.01.2009 V.Ivanchenko move constructor and destructor to source,
|
|
// use STL vector instead of C-array
|
|
//
|
|
// August 2011 Re-designed
|
|
// by G. Folger, V. Ivantchenko, T. Koi and D.H. Wright
|
|
|
|
// Class Description
|
|
// This is the class to which cross section data sets may be registered.
|
|
// An instance of it is contained in each hadronic process, allowing
|
|
// the use of the AddDataSet() method to tailor the cross sections to
|
|
// your application.
