Constructor & Destructor Documentation

IlvDoublePoint::IlvDoublePoint	(	IlDouble	x = (IlDouble)0,
		IlDouble	y = (IlDouble)0
	)

Constructor.

Initializes a new IlvDoublePoint with the indicated coordinates. point. Its parameters represent the x and y coordinates of the floating point.

Member Function Documentation

IlDouble IlvDoublePoint::getX

(

)

const

Gets the x point coordinate.

Returns

The x point coordinate.

IlDouble IlvDoublePoint::getY

(

)

const

Gets the y point coordinate.

Returns

The y point coordinate.

void IlvDoublePoint::move	(	IlDouble	newX,
		IlDouble	newY
	)

Moves the point.

Parameters

newX	The x point coordinate.
newY	The y point coordinate.

int IlvDoublePoint::operator!=

(

const IlvDoublePoint &

p

)

const

Tests points for inequality.

Returns

0 if p is the same as the current object.

IlvDoublePoint& IlvDoublePoint::operator=

(

const IlvDoublePoint &

p

)

Copies a point.

Copies p to the current object.

Parameters

p	The source point.

int IlvDoublePoint::operator==

(

const IlvDoublePoint &

p

)

const

Tests points for equality.

Returns

0 if p is different from the current object.

void IlvDoublePoint::set	(	IlDouble	newX,
		IlDouble	newY
	)

Sets the point coordinates.

Parameters

newX	The x point coordinate.
newY	The y point coordinate.

void IlvDoublePoint::setX

(

IlDouble

newX

)

Sets the x point coordinate.

Parameters

newX	The x point coordinate.

void IlvDoublePoint::setY

(

IlDouble

newY

)

Sets the y point coordinate.

Parameters

newY	The y point coordinate.

void IlvDoublePoint::translate	(	IlDouble	dx,
		IlDouble	dy
	)

Moves the object by relative translation.

Shifts an existing point to another location by means of a delta-distance approach. That is, you indicate the dx and dy values that represent the distance between the current position of the point and the target future position.

Parameters

dx	The x delta offset.
dy	The y delta offset.
