Member Function Documentation

virtual bool fastjet::RangeDefinition::is_localizable ( ) const

inlinevirtual

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 95 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???

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.
