 RangeDefinition ()
 default constructor
 RangeDefinition (double rapmax)
 constructor for a range definition given by |y|<rapmax
virtual ~RangeDefinition ()
 destructor does nothing
 RangeDefinition (double rapmin, double rapmax, double phimin=0.0, double phimax=twopi)
 constructor for a range definition given by rapmin <= y <= rapmax, phimin <= phi <= phimax
virtual bool is_localizable () const
 returns true if the range is localizable (i.e.
void set_position (const double &rap, const double &phi)
 place the range on the rap-phi position
void set_position (const PseudoJet &jet)
 place the range on the jet position
bool is_in_range (const PseudoJet &jet) const
 return bool according to whether the jet is within the given range
virtual bool is_in_range (double rap, double phi) const
 return bool according to whether a (rap,phi) point is in range
virtual void get_rap_limits (double &rapmin, double &rapmax) const
 return the minimal and maximal rapidity of this range; remember to replace this if you write a derived class with more complex ranges;
virtual double area () const
 area of the range region
virtual std::string description () const
 textual description of range

Protected Member Functions

void _numerical_total_area (double rapmax, int npoints)
 calculate, and set _total_area, by calculating which of points on a grid (npoints * npoints from -rapmax..rapmax,0..2pi) are contained in the range; it takes a reasonable time with rapmax = 10, npoints = 100.

Member Function Documentation

virtual bool fastjet::RangeDefinition::is_localizable ( ) const [inline, virtual]

returns true if the range is localizable (i.e.

set_position is meant to do something meaningful).

This version of the class is not localizable and so it returns false.

For localizable classes override this function with a function that returns true

Definition at line 93 of file RangeDefinition.hh.

void fastjet::RangeDefinition::set_position ( const double &  rap,
const double &  phi 
) [inline]

place the range on the rap-phi position

THIS DOES NOT DO ANYTHING FOR THIS CLASS AND IS ONLY THERE TO FACILITATE DERIVED CLASSES

DON'T NECESSARILY COUNT ON IT IN THE FUTURE EITHER???

void fastjet::RangeDefinition::_numerical_total_area ( double  rapmax,
int  npoints 
) [protected]

calculate, and set _total_area, by calculating which of points on a grid (npoints * npoints from -rapmax..rapmax,0..2pi) are contained in the range; it takes a reasonable time with rapmax = 10, npoints = 100.
