Member Function Documentation

void IlvMapMultiPoint::addPoint

(

const IlvCoordinate &

c

)

Adds a coordinate at the end of the multipoint.

Parameters:

c

The 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:

index

The 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 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.

Implements IlvMapGeometry.

virtual IlUInt IlvMapMultiPoint::getSubElementCount

(

)

const [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.

Implements IlvMapGeometry.

virtual IlBoolean IlvMapMultiPoint::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.

Returns:

IlTrue if the geometry is a collection of other geometries.

Implements IlvMapGeometry.
