Constructor & Destructor Documentation

IlvMapMultiPoint()

IlvMapMultiPoint::IlvMapMultiPoint

(

const IlvMapMultiPoint &

source

)

Initializes a new multipoint by copying an existing one.

Parameters

source

The source multipoint.

Member Function Documentation

addPoint()

void IlvMapMultiPoint::addPoint

(

const IlvCoordinate &

c

)

Adds a coordinate at the end of the multipoint.

Parameters

c	The coordinate.

copy()

virtual IlvMapGeometry* IlvMapMultiPoint::copy ( ) const

virtual

Returns a copy of the object.

Returns

An IlvMapGeometry that must be deleted by the user.

Implements IlvMapGeometry.

getClassInfo()

virtual IlvClassInfo* IlvMapMultiPoint::getClassInfo ( ) const

virtual

Returns the IlvClassInfo of the instance.

Returns

An IlvClassInfo that should not be modified nor deleted.

Implements IlvMapGeometry.

getPoint()

const IlvCoordinate& IlvMapMultiPoint::getPoint

(

IlUInt

index

)

const

Returns the coordinate at a specified index.

Parameters

index

The index.

Returns

The coordinate of the specified index.

getPointCount()

IlUInt IlvMapMultiPoint::getPointCount

(

)

const

Returns the number of points in the multipoint.

Returns

The number of points in the multipoint.

getSubElement()

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

virtual

Returns a sub element of a collection geometry.

Parameters

index

The 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 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.

isCollection()

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.
