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

Constructor & Destructor Documentation

IlvMapGeometryCollection::IlvMapGeometryCollection

(

)

Constructor.

Creates an IlvMapGeometryCollection.

IlvMapGeometryCollection::IlvMapGeometryCollection

(

const IlvMapGeometryCollection &

source

)

Creates an IlvMapGeometryCollection by copying an existing one.

Parameters

source

The object to be copied.

Member Function Documentation

void IlvMapGeometryCollection::addGeometry

(

IlvMapGeometry *

geometry

)

Adds a geometry at the end of the collection. The collection becomes owner of the geometry.

Parameters

geometry

The geometry to be added.

virtual IlvMapGeometry* IlvMapGeometryCollection::copy ( ) const

virtual

Returns a copy of the object.

Returns

An IlvMapGeometry that must be deleted by the user.

Implements IlvMapGeometry.

virtual IlvClassInfo* IlvMapGeometryCollection::getClassInfo ( ) const

virtual

Returns the IlvClassInfo of the instance.

Returns

An IlvClassInfo that should not be modified nor deleted.

Implements IlvMapGeometry.

virtual const IlvMapGeometry* IlvMapGeometryCollection::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.

virtual IlUInt IlvMapGeometryCollection::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 IlvMapGeometryCollection::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.
