Member Function Documentation

§ copy()

virtual IlvMapGeometry* IlvMapPoint::copy ( ) const
virtual

Returns a copy of the object.

Returns
An IlvMapGeometry that must be deleted by the user.

Implements IlvMapGeometry.

§ getClassInfo()

virtual IlvClassInfo* IlvMapPoint::getClassInfo ( ) const
virtual

Returns the IlvClassInfo of the instance.

Returns
An IlvClassInfo that should not be modified nor deleted.

Implements IlvMapGeometry.

§ getPoint()

const IlvCoordinate& IlvMapPoint::getPoint ( ) const

Returns the position of the point.

Returns
The position of the point.

§ getSubElement()

virtual const IlvMapGeometry* IlvMapPoint::getSubElement ( IlUInt  index) const
virtual

Returns a sub element of a collection geometry.

Parameters
indexThe index of the sub-geometry to be retrieved.
Returns
The sub element of index index if the geometry is a collection or 0 if it is not.

Implements IlvMapGeometry.

§ getSubElementCount()

virtual IlUInt IlvMapPoint::getSubElementCount ( ) const
virtual

Returns the number of elements contained in the geometry if the geometry is a collection.

Returns
The number of elements contained in the geometry if the geometry is a collection. If it is not, this method returns 0.

Implements IlvMapGeometry.

§ isCollection()

virtual IlBoolean IlvMapPoint::isCollection ( ) const
virtual

Checks if this 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.

Returns
IlTrue if the geometry is a collection of other geometries.

Implements IlvMapGeometry.

§ setPoint()

void IlvMapPoint::setPoint ( const IlvCoordinate point)

Changes the value of the coordinate.

Parameters
pointThe coordinate of the point. The object is not copied.
