// Class Description: 
//
// Class provide access to the cross section data stored in the G4LEDATA
// data structure in form of G4PhysicsVector. For that data are uploaded
// to the G4ElementData via G4ElementDataRegistry allowing sharing of
// data between threads.
//
// When retrieve data, this class set mutex lock.
