Member Function Documentation

template<typename T>

void Geom::Piecewise< T >::push	(	const T &	s,
		double	to
	)

inline

Convenience/implementation hiding function to add segment/cut pairs. Asserts that basic size and order invariants are correct

template<typename T>

unsigned Geom::Piecewise< T >::segN	(	double	t,
		int	low = `0`,
		int	high = `-1`
	)		const

inline

Returns the segment index which corresponds to a 'global' piecewise time. Also takes optional low/high parameters to expedite the search for the segment.

template<typename T>

double Geom::Piecewise< T >::segT	(	double	t,
		int	i = `-1`
	)		const

inline

Returns the time within a segment, given the 'global' piecewise time. Also takes an optional index parameter which may be used for efficiency or to find the time on a segment outside its range. If it is left to its default, -1, it will call segN to find the index.
