Detailed Description

Geometric class.

Library: display

The IlvDoublePoint class deals with floating point coordinate values coded on a double-precision floating number.

See Also
IlvPoint, IlvFloatPoint.

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
newXThe x point coordinate.
newYThe 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
pThe 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
newXThe x point coordinate.
newYThe y point coordinate.
void IlvDoublePoint::setX ( IlDouble  newX)

Sets the x point coordinate.

Parameters
newXThe x point coordinate.
void IlvDoublePoint::setY ( IlDouble  newY)

Sets the y point coordinate.

Parameters
newYThe 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
dxThe x delta offset.
dyThe y delta offset.
