Detailed Description

This class defines a multipoint, which is a collection of points.

The instances of this class can be rendered by an IlvDefaultFeatureRenderer. Library: ilvmaps

Constructor & Destructor Documentation

IlvMapMultiPoint::IlvMapMultiPoint ( )

Constructor.

Initializes an instance of the class.

IlvMapMultiPoint::IlvMapMultiPoint ( const IlvMapMultiPoint source)

Creates a multipoint by copying an existing one.

Parameters
sourceThe source multipoint.

Member Function Documentation

void IlvMapMultiPoint::addPoint ( const IlvCoordinate c)

Adds a coordinate at the end of the multipoint.

Parameters
cThe coordinate.
virtual IlvMapGeometry* IlvMapMultiPoint::copy ( ) const
virtual

Returns a copy of the object.

Returns
An IlvMapGeometry that must be deleted by the user.

Implements IlvMapGeometry.

virtual IlvClassInfo* IlvMapMultiPoint::getClassInfo ( ) const
virtual

Returns the IlvClassInfo of the instance.

Returns
An IlvClassInfo that should not be modified nor deleted.

Implements IlvMapGeometry.

const IlvCoordinate& IlvMapMultiPoint::getPoint ( IlUInt  index) const

Returns the coordinate of the specified index.

Parameters
indexThe index.
Returns
The coordinate of the specified index.
IlUInt IlvMapMultiPoint::getPointCount ( ) const

Returns the number of points in the multipoint.

Returns
The number of points in the multipoint.
virtual const IlvMapGeometry* IlvMapMultiPoint::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.

virtual IlUInt IlvMapMultiPoint::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.

virtual IlBoolean IlvMapMultiPoint::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.
