Detailed Description

This class defines a ring whose stroke is an IlvMapCircle.

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

Constructor & Destructor Documentation

IlvMapCircularRing::IlvMapCircularRing ( IlvMapCircle stroke)

Initializes an instance of the class with its stroke.

Parameters
strokeThe stroke. This parameter should not be null. The IlvMapCircularRing becomes owner of stroke.
IlvMapCircularRing::IlvMapCircularRing ( const IlvMapCircularRing source)

Creates a ring by copying an existing one.

Parameters
sourceThe source segment ring.

Member Function Documentation

virtual IlBoolean IlvMapCircularRing::contains ( const IlvCoordinate coordinate) const
virtual

Returns IlTrue if coordinate is contained in the object.

Parameters
coordinateThe point to be checked.
Returns
IlTrue if coordinate is contained in the object.

Implements IlvMapRing.

virtual IlvMapGeometry* IlvMapCircularRing::copy ( ) const
virtual

Returns a copy of the object.

Returns
An IlvMapGeometry that must be deleted by the user.

Implements IlvMapRing.

const IlvMapCircle* IlvMapCircularRing::getCircularStroke ( ) const

Returns the stroke of the object.

Returns
The stroke of the object.
virtual IlvClassInfo* IlvMapCircularRing::getClassInfo ( ) const
virtual

Returns the IlvClassInfo of the instance.

Returns
An IlvClassInfo that should not be modified nor deleted.

Implements IlvMapRing.

virtual const IlvMapCurve* IlvMapCircularRing::getStroke ( ) const
virtual

Returns the stroke of the area.

Returns
An IlvCurve object that should not be deleted nor modified.

Implements IlvMapRing.

virtual const IlvMapGeometry* IlvMapCircularRing::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 IlvMapCircularRing::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 IlvMapCircularRing::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.

IlvMapCircle* IlvMapCircularRing::setStroke ( IlvMapCircle stroke)

Sets the stroke of the object.

Parameters
strokeThe new stroke. In this operation, the IlvMapCircularRing object becomes owner of stroke.
Returns
The previous stroke that must be deleted by the user.
