Constructor & Destructor Documentation

TUIO::TuioPoint::TuioPoint	(	float	xp,
		float	yp
	)		`[inline]`

The default constructor takes no arguments and sets its coordinate attributes to zero and its time stamp to the current session time.

TUIO::TuioPoint::TuioPoint	(	TuioTime	ttime,
		float	xp,
		float	yp
	)		`[inline]`

This constructor takes a TuioTime object and two floating point coordinate arguments and sets its coordinate attributes to these values and its time stamp to the provided TUIO time object.

Parameters:

ttime	the TuioTime to assign
xp	the X coordinate to assign
yp	the Y coordinate to assign

TUIO::TuioPoint::TuioPoint ( TuioPoint * tpoint ) [inline]

This constructor takes a TuioPoint argument and sets its coordinate attributes to the coordinates of the provided TuioPoint and its time stamp to the current session time.

Parameters:

tpoint the TuioPoint to assign

TUIO::TuioPoint::~TuioPoint ( ) [inline]

The destructor is doing nothing in particular.
