Constructor & Destructor Documentation

line_t() [1/2]

JetGeom::line_t::line_t ( float cx, float cy, float cc, bool to_r )

inline

constructor by giving the coeff of equation of the line (

Parameters

cx	x +
cy	y +
cc	= 0). If
to_r	is true the line is oriented toward positive x

Definition at line 43 of file cyl_geom.h.

: m_cx(cx),m_cy(cy),m_cc(cc), m_oriented_r(to_r) {};

line_t() [2/2]

JetGeom::line_t::line_t ( point_t p1, point_t p2 )

inline

Constructor by giving 2 points.

This also sets orientation

  m_cy = p1.first - p2.first;
  m_cx = p2.second - p1.second;
  m_cc = -(m_cx*p1.first+m_cy*p1.second);  
  m_oriented_r = (p1.first < p2.first);
