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::IlvMapMultiCurve

(

)

Constructor.

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

IlvMapMultiCurve::IlvMapMultiCurve

(

const IlvMapMultiCurve &

source

)

Creates a multi curve by copying an existing one.

Parameters

source

The object to be copied.

Member Function Documentation

void IlvMapMultiCurve::addCurve

(

IlvMapCurve *

curve

)

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

Parameters

curve

The curve to be added.

virtual IlvMapGeometry* IlvMapMultiCurve::copy ( ) const

virtual

Returns a copy of the object.

Returns

An IlvMapGeometry that must be deleted by the user.

Implements IlvMapCurve.

IlUInt IlvMapMultiCurve::getCardinal

(

)

const

Returns the number of curves.

Returns

The number of curves.

virtual IlvClassInfo* IlvMapMultiCurve::getClassInfo ( ) const

virtual

Returns the IlvClassInfo of the instance.

Returns

An IlvClassInfo that should not be modified nor deleted.

Implements IlvMapCurve.

const IlvMapCurve* IlvMapMultiCurve::getCurve

(

IlUInt

i

)

const

Returns the curve of index i.

Parameters

i	The index that must be between 0 and getCardinal() - 1

Returns

An IlvMapCurve object that should not be modified nor deleted.

virtual const IlvMapGeometry* IlvMapMultiCurve::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 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.

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.

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

curve

The 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.
