CustomPhysicsTable.hh

Go to the documentation of this file.

//
//
// The custom physics table keeps track of all compiled physics modules and feeds their
// names and constructors to the ConfigurablePhysicsList.
//
// A CustomPhysicsTable is instantiated in the constructor of each CustomPhysicsFactory<T>
// with a pointer to the instantiating factory as an argument.  This pointer is passed to
// a singleton, static CustomPhysicsTable called TheCustomPhysicsTable.  It is this table
// which the ConfigurablePhysicsList interacts with.
//
// At runtime the CustomPhysicsTable contains an array of CustomPhysicsFactories, one
// for each available physics module, and can provide the list of their names and
// the constructor for each to the physics list.
//
// This means new physics modules can be enabled via the LArG4.xml file with no change to
// the physics list code
//
// See CustomPhysicsFactory.hh and CustomPhysicsFactory.cxx for more details.
