Constructor & Destructor Documentation

JUniformGenerator() [1/2]

JMARKOV::JUniformGenerator::JUniformGenerator ( double xmin, double ymin, double zmin, double xmax, double ymax, double zmax )

inline

Constructor.

The arguments are the limits of each coordinate.

Definition at line 71 of file JMarkovGenerator.hh.

                                                                                                      : posmin(xmin,ymin,zmin), posmax(xmax,ymax,zmax) {
      setVolume() ;
    }

JUniformGenerator() [2/2]

JMARKOV::JUniformGenerator::JUniformGenerator ( JPosition3D _posmin, JPosition3D _posmax )

inline

Constructor.

The arguments are the 'lower left bottom' corner and the 'upper right top' corner.

Definition at line 79 of file JMarkovGenerator.hh.

                                                                  : posmin(_posmin), posmax(_posmax) {
      setVolume() ;
    }

Member Function Documentation

getPosition()

JPosition3D JMARKOV::JUniformGenerator::getPosition ( )

inlinevirtual

Return a randomly generated position.

Implements JMARKOV::JGenerator.

Definition at line 83 of file JMarkovGenerator.hh.

                              {
      double x = gRandom->Uniform( posmin.getX(), posmax.getX() ) ;
      double y = gRandom->Uniform( posmin.getY(), posmax.getY() ) ;
      double z = gRandom->Uniform( posmin.getZ(), posmax.getZ() ) ;
      return JPosition3D(x,y,z) ;
    }

getWeight()

double JMARKOV::JUniformGenerator::getWeight ( JPosition3D pos )

inlinevirtual

return the weight (=probability density dP/dV) for the given position.

When the generator is properly normalized, the integral of this quantity over the whole space is 1.

Implements JMARKOV::JGenerator.

Definition at line 90 of file JMarkovGenerator.hh.

                                        {
      if( pos.getX() < posmin.getX() ||  pos.getX() > posmax.getX() ) return 0.0 ;
      if( pos.getY() < posmin.getY() ||  pos.getY() > posmax.getY() ) return 0.0 ;
      if( pos.getZ() < posmin.getZ() ||  pos.getZ() > posmax.getZ() ) return 0.0 ;
      return 1.0/V ;
    }

setVolume()

void JMARKOV::JUniformGenerator::setVolume ( )

inlineprotected

Definition at line 99 of file JMarkovGenerator.hh.

                     {
      V = (posmax.getX()-posmin.getX())*(posmax.getY()-posmin.getY())*(posmax.getZ()-posmin.getZ()) ;
