Detailed Description

This abstract class is the base class of the map geometry objects.

The IlvMapGeometry classes represent the shape of the map features. There is a list of predefined geometries in the package ilog.views.maps.geometry. The instances of the predefined subclasses of IlvMapGeometry can be rendered by an IlvDefaultFeatureRenderer. Library: ilvmaps

Constructor & Destructor Documentation

IlvMapGeometry::IlvMapGeometry ( )

protected

Constructor.

Initializes an instance of the class.

Member Function Documentation

static IlvClassInfo* IlvMapGeometry::ClassInfo ( )

static

Returns the class info.

This static function, redefined for each subclass of IlvMapGeometry returns the IlvClassInfo of the class.

Returns

An IlvClassInfo that should not be modified nor deleted.

virtual IlvMapGeometry* IlvMapGeometry::copy ( ) const

pure virtual

Returns a copy of the object.

Returns

An IlvMapGeometry that must be deleted by the user.

Implemented in IlvMapRaster, IlvMapPolygon, IlvMapLineString, IlvMapSegmentString, IlvMapImage, IlvMapMultiArea, IlvMapMultiCurve, IlvMapArcString, IlvMapArcSegment, IlvMapText, IlvMapCircle, IlvMapMultiPoint, IlvMapSegment, IlvMapSegmentRing, IlvMapPoint, IlvMapCurveString, IlvMapCircularRing, IlvMapGeometryCollection, IlvMapLinearSegment, IlvMapArea, IlvMapCurve, and IlvMapRing.

virtual IlvClassInfo* IlvMapGeometry::getClassInfo ( ) const

pure virtual

Returns the IlvClassInfo of the instance.

Returns

An IlvClassInfo that should not be modified nor deleted.

Implemented in IlvMapRaster, IlvMapPolygon, IlvMapLineString, IlvMapSegmentString, IlvMapImage, IlvMapMultiArea, IlvMapMultiCurve, IlvMapArcString, IlvMapArcSegment, IlvMapText, IlvMapCircle, IlvMapMultiPoint, IlvMapSegmentRing, IlvMapPoint, IlvMapCurveString, IlvMapCircularRing, IlvMapGeometryCollection, IlvMapLinearSegment, IlvMapArea, IlvMapCurve, and IlvMapRing.

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

pure virtual

Returns the sub element of index index if the geometry is a collection.

Otherwise, it returns a null pointer.

Returns

The sub element of index index if the geometry is a collection.

Implemented in IlvMapRaster, IlvMapPolygon, IlvMapSegmentString, IlvMapImage, IlvMapMultiArea, IlvMapMultiCurve, IlvMapArcSegment, IlvMapText, IlvMapCircle, IlvMapMultiPoint, IlvMapSegmentRing, IlvMapPoint, IlvMapCircularRing, IlvMapGeometryCollection, and IlvMapLinearSegment.

virtual IlUInt IlvMapGeometry::getSubElementCount ( ) const

pure virtual

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

Otherwise, it returns 0.

Returns

The number of elements contained in the geometry if the geometry is a collection. Otherwise, it returns 0.

Implemented in IlvMapRaster, IlvMapPolygon, IlvMapSegmentString, IlvMapImage, IlvMapMultiArea, IlvMapMultiCurve, IlvMapArcSegment, IlvMapText, IlvMapCircle, IlvMapMultiPoint, IlvMapSegmentRing, IlvMapPoint, IlvMapCircularRing, IlvMapGeometryCollection, and IlvMapLinearSegment.

virtual IlBoolean IlvMapGeometry::isCollection ( ) const

pure 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.

Returns

IlTrue if the geometry is a collection of other geometries.

Implemented in IlvMapRaster, IlvMapPolygon, IlvMapSegmentString, IlvMapImage, IlvMapMultiArea, IlvMapMultiCurve, IlvMapArcSegment, IlvMapText, IlvMapCircle, IlvMapMultiPoint, IlvMapSegmentRing, IlvMapPoint, IlvMapCircularRing, IlvMapGeometryCollection, and IlvMapLinearSegment.
