IlvMapPoint::IlvMapPoint | ( | ) |
Constructor.
Initializes an instance of IlvMapPoint
.
IlvMapPoint::IlvMapPoint | ( | const IlvMapPoint & | source | ) |
Creates a point by copying an existing point.
source | The source point. |
IlvMapPoint::IlvMapPoint | ( | const IlvCoordinate & | point | ) |
Initializes an IlvMapPoint
with the specified coordinate.
point | The coordinate of the point. The object is not copied. |
virtual IlvMapGeometry* IlvMapPoint::copy | ( | ) | const [virtual] |
Returns a copy of the object.
IlvMapGeometry
that must be deleted by the user. Implements IlvMapGeometry.
virtual IlvClassInfo* IlvMapPoint::getClassInfo | ( | ) | const [virtual] |
Returns the IlvClassInfo
of the instance.
IlvClassInfo
that should not be modified nor deleted. Implements IlvMapGeometry.
const IlvCoordinate& IlvMapPoint::getPoint | ( | ) | const |
Returns the position of the point.
virtual const IlvMapGeometry* IlvMapPoint::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 IlvMapPoint::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 IlvMapPoint::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.
void IlvMapPoint::setPoint | ( | const IlvCoordinate & | point | ) |
Changes the value of the coordinate.
point | The coordinate of the point. The object is not copied. |
