Point class

A Point class represents a coordinate or xy pair.

 

Point::Point()

Creates a Point object p. The Point is initialised to (0, 0) by default.

 

Point::Point(int32_t x, int32_t y)

Creates a Point object and initialises its coordinates.

 

int32_t Point::getX()

int32_t Point::getY()

Get the specified Point coordinate.

 

Point::setX(int32_t x)

Point::setY(int32_t y)

Point::setCoord(int32_t x, int32_t y)

Set the specified Point coordinate.

 

Point::operator == (const Point &other)

Returns true if the two Points are equal.

 

Point::operator !=

Returns true if the two Points are not equal.

 

Point::operator <

Returns true if the first point is 'less than' the second. First the X coordinate is compared; if equal then the Y coordinate is compared.

 

Point::operator >

Returns true if the first point is 'greater than' the second. First the X coordinate is compared; if equal then the Y coordinate is compared.

 

Point::operator +

A Point plus a Vector returns a Point transposed by the Vector.

A Point plus a Point returns a Point transposed by the Point.

 

Point::operator -

A Point minus a Point returns a Vector.

 

Point::operator -

A Point minus a Vector returns a Point transposed by the Vector.

 

Point::operator +=

A Point plus a scalar (i.e. an integer) is offset, or moved, by the value of the scalar in both X and Y.

A Point plus a Point returns a Point with the sum of the two Points X and Y values.

 

Point::operator -=

A Point minus a Point returns a Point with the differrence of the two Points X and Y values.

 

Point::operator *=

A Point times a scalar is scaled (multiplied) by the scalar.
