// Hadronic Interaction abstract base class
|
|
// This class is the base class for the model classes.
|
|
// It sorts out the energy-range for the models and provides
|
|
// class utilities.
|
|
// original by H.P. Wellisch
|
|
// Modified by J.L.Chuma, TRIUMF, 21-Mar-1997
|
|
// Last modified: 3-Apr-1997
|
|
// Added units to energy initialization: J.L. Chuma 04-Apr-97
|
|
// Modified by J.L.Chuma, 05-May-97 to Initialize theBlockedCounter
|
|
// Modified by J.L.Chuma, 08-Jul-97 to implement the Nucleus changes
|
|
// Adding a registry for memory management of hadronic models, HPW 22-Mar-99
|
|
// 23-Jan-2009 V.Ivanchenko move constructor and destructor to the body
|
|
// and reorder methods in the header
|
|
// 29-Jun-2009 V.Ivanchenko add SampleInvariantT method
|
|
// 29-Aug-2009 V.Ivanchenko moved G4ReactionDynamics to G4InelasticInteraction,
|
|
// add const pointers, and added recoilEnergyThreshold
|
|
// member and accesors
|
|
|
|
// Class Description
|
|
// This is the base class for all hadronic interaction models in geant4.
|
|
// If you want to implement a new way of producing a final state, please,
|
|
// inherit from here.
