Member Function Documentation

UPoint ufo::UPoint::getLocation (   )  const [inline]

Returns a copy. For convenience

bool ufo::UPoint::isInvalid (   )  const [inline]

Returns: True if the width and height are equal to invalid See also: invalid

bool ufo::UPoint::isNull (   )  const [inline]

Returns: True if both, x and y are exactly 0.

UPoint & ufo::UPoint::operator *= (  double  c  )  [inline]

Multiplies c to both x and y coordinate of this point. Truncates the values to integers. Returns: Reference to this point.

UPoint & ufo::UPoint::operator *= (  int  c  )  [inline]

Multiplies c to both x and y coordinate of this point. Returns: Reference to this point.

UPoint & ufo::UPoint::operator+= (  const UPoint &  p  )  [inline]

Adds point p to this point Returns: Reference to this point.

UPoint & ufo::UPoint::operator-= (  const UPoint &  p  )  [inline]

Subtracts point p from this point Returns: Reference to this point.

UPoint & ufo::UPoint::operator/= (  double  c  )  [inline]

Divides both x and y by c. Truncates the values to integers. Returns: Reference to this point.

UPoint & ufo::UPoint::operator/= (  int  c  )  [inline]

Divides both x and y by c. Truncates the values to integers. Returns: Reference to this point.

void ufo::UPoint::setLocation (  const UPoint &  p  )  [inline]

for convenience

void ufo::UPoint::translate (  const UPoint &  p  )  [inline]

This method is for convenience. It adds p to this point.
