IlvMapMultiArea::IlvMapMultiArea | ( | ) |
Constructor.
Initializes an instance of the class.
IlvMapMultiArea::IlvMapMultiArea | ( | const IlvMapMultiArea & | source | ) |
Creates a multi area by copying an existing one.
source | The source area. |
void IlvMapMultiArea::addArea | ( | IlvMapArea * | area | ) |
Adds an area. In this operation, the multi area becomes owner of the area.
area | The area to be added. |
|
virtual |
Returns IlTrue
if coordinate is contained in the object.
coordinate | The point to be checked. |
IlTrue
if coordinate is contained in the object. Implements IlvMapArea.
|
virtual |
Returns a copy of the object.
IlvMapGeometry
that must be deleted by the user. Implements IlvMapArea.
const IlvMapArea* IlvMapMultiArea::getArea | ( | IlUInt | i | ) | const |
Returns the area of index i.
i | The index that should be between 0 and getCardinal() - 1 |
IlvMapArea
object that should not be modified nor deleted. IlUInt IlvMapMultiArea::getCardinal | ( | ) | const |
Returns the number of areas.
|
virtual |
Returns the IlvClassInfo
of the instance.
IlvClassInfo
that should not be modified nor deleted. Implements IlvMapArea.
|
virtual |
Returns the stroke of the area.
IlvCurve
object that should not be deleted nor modified. Implements IlvMapArea.
|
virtual |
Returns a sub element of a collection geometry.
index | The index of the sub-geometry to be retrieved. |
0
if it is not. Implements IlvMapGeometry.
|
virtual |
Returns the number of elements contained in the geometry if the geometry is a collection.
0
. Implements IlvMapGeometry.
|
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
.
IlTrue
if the geometry is a collection of other geometries. Implements IlvMapGeometry.
IlvMapArea* IlvMapMultiArea::removeArea | ( | const IlvMapArea * | area | ) |
Removes the specified area and returns it.
If the area is not part of the multi area, the function returns a null pointer.
area | A null pointer if area is not a member of the object, or an IlvMapArea that should be deleted by the user. |
