Detailed Description

This class is used to represent 1-dimension geometries that are composed of a list of other curves.

IlvMapMultiCurve does not have to be connected. The instances of this class can be rendered by an IlvDefaultFeatureRenderer or by an IlvDefaultCurveRenderer. Library: ilvmaps

Constructor & Destructor Documentation

§ IlvMapMultiCurve() [1/2]

IlvMapMultiCurve::IlvMapMultiCurve ( )

Constructor.

Initializes an instance of the class with an empty list of curves.

§ IlvMapMultiCurve() [2/2]

IlvMapMultiCurve::IlvMapMultiCurve ( const IlvMapMultiCurve source)

Creates a multi curve by copying an existing one.

Parameters
sourceThe object to be copied.

Member Function Documentation

§ addCurve()

void IlvMapMultiCurve::addCurve ( IlvMapCurve curve)

Adds a curve. In this operation, the IlvMapMultiCurve object becomes owner of curve.

Parameters
curveThe curve to be added.

§ copy()

virtual IlvMapGeometry* IlvMapMultiCurve::copy ( ) const
virtual

Returns a copy of the object.

Returns
An IlvMapGeometry that must be deleted by the user.

Implements IlvMapCurve.

§ getCardinal()

IlUInt IlvMapMultiCurve::getCardinal ( ) const

Returns the number of curves.

Returns
The number of curves.

§ getClassInfo()

virtual IlvClassInfo* IlvMapMultiCurve::getClassInfo ( ) const
virtual

Returns the IlvClassInfo of the instance.

Returns
An IlvClassInfo that should not be modified nor deleted.

Implements IlvMapCurve.

§ getCurve()

const IlvMapCurve* IlvMapMultiCurve::getCurve ( IlUInt  i) const

Returns the curve of index i.

Parameters
iThe index that must be between 0 and getCardinal() - 1
Returns
An IlvMapCurve object that should not be modified nor deleted.

§ getSubElement()

virtual const IlvMapGeometry* IlvMapMultiCurve::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.

§ getSubElementCount()

virtual IlUInt IlvMapMultiCurve::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 IlvMapMultiCurve::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.

§ removeCurve()

IlvMapCurve* IlvMapMultiCurve::removeCurve ( const IlvMapCurve curve)

Removes the specified curve and returns it.

If the curve is not part of the multi curve, the function returns a null pointer.

Parameters
curveThe curve to be removed.
Returns
A null pointer if curve is not a member of the IlvMapMultiCurve object, or an IlvMapCurve that has to be deleted by the user.
