IlvMapCircle::IlvMapCircle | ( | const IlvCoordinate & | center, | |
IlDouble | radius | |||
) |
Initializes an instance of circle by specifying its center and its radius.
center | The center of the circle. | |
radius | The radius of the circle. |
IlvMapCircle::IlvMapCircle | ( | const IlvCoordinate & | control1, | |
const IlvCoordinate & | control2, | |||
const IlvCoordinate & | control3 | |||
) |
Initializes an instance of IlvMapCircle
by giving the three different points that are on the circle.
control1 | First control point. | |
control2 | Second control point. | |
control3 | Third control point. |
virtual IlvMapGeometry* IlvMapCircle::copy | ( | ) | const [virtual] |
Returns a copy of the object.
IlvMapGeometry
that must be deleted by the user. Implements IlvMapCurve.
const IlvCoordinate& IlvMapCircle::getCenter | ( | ) | const |
Returns the center of the circle.
virtual IlvClassInfo* IlvMapCircle::getClassInfo | ( | ) | const [virtual] |
Returns the IlvClassInfo
of the instance.
IlvClassInfo
that should not be modified nor deleted. Implements IlvMapCurve.

Returns the radius of the circle.
virtual const IlvMapGeometry* IlvMapCircle::getSubElement | ( | IlUInt | index | ) | const [virtual] |
Returns the sub element of index index if the geometry is a collection.
Otherwise, it returns a null pointer.
Implements IlvMapGeometry.
virtual IlUInt IlvMapCircle::getSubElementCount | ( | ) | const [virtual] |
Returns the number of elements contained in the geometry if the geometry is a collection.
Otherwise, it returns 0
.
0
. Implements IlvMapGeometry.
virtual IlBoolean IlvMapCircle::isCollection | ( | ) | const [virtual] |
Returns IlTrue
if the geometry is a collection of other geometries.
The composite geometries predefined in Rogue Wave Views Maps are: IlvMapGeometryCollection, IlvMapMultiPoint, IlvMapSegmentString
and its subclasses, IlvMapMultiCurve
and IlvMapMultiArea
.
IlTrue
if the geometry is a collection of other geometries. Implements IlvMapGeometry.
