size_t G4PhysicsLnVector::FindBinLocation

(

G4double

theEnergy

)

const [protected, virtual]

Implements G4PhysicsVector.

Definition at line 113 of file G4PhysicsLnVector.cc.

References G4PhysicsVector::baseBin, and G4PhysicsVector::dBin.

{
 
  // For G4PhysicsLnVector, FindBinLocation is implemented using
  // a simple arithmetic calculation.
  //
  // Because this is a virtual function, it is accessed through a
  // pointer to the G4PhyiscsVector object for most usages. In this
  // case, 'inline' will not be invoked. However, there is a possibility 
  // that the user access to the G4PhysicsLnVector object directly and 
  // not through pointers or references. In this case, the 'inline' will
  // be invoked. (See R.B.Murray, "C++ Strategies and Tactics", Chap.6.6)

  return size_t( std::log(theEnergy)/dBin - baseBin );
