Constructor & Destructor Documentation

IlvMapPoint() [1/3]

IlvMapPoint::IlvMapPoint

(

)

Constructor.

Initializes an instance of IlvMapPoint.

IlvMapPoint() [2/3]

IlvMapPoint::IlvMapPoint

(

const IlvMapPoint &

source

)

Creates a point by copying an existing point.

Parameters

source

The source point.

IlvMapPoint() [3/3]

IlvMapPoint::IlvMapPoint

(

const IlvCoordinate &

point

)

Initializes an IlvMapPoint with the specified coordinate.

Parameters

point

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

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

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 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

point

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