This abstract class is the base class for segments that can be divided into other smaller segments.
Library: ilvmaps
The IlvMapCurveString is a generic implementation that can handle any type of IlvMapSegment, while other subclasses are optimized to handle uniform lists of segments.
The instances of the predefined subclasses of IlvMapSegmentString can be rendered by an IlvDefaultFeatureRenderer or by an IlvDefaultCurveRenderer.
|
pure virtual |
Returns a copy of the object.
IlvMapGeometry that must be deleted by the user. Implements IlvMapSegment.
Implemented in IlvMapLineString, IlvMapArcString, and IlvMapCurveString.
|
pure virtual |
Returns the IlvClassInfo of the instance.
IlvClassInfo that should not be modified nor deleted. Implements IlvMapCurve.
Implemented in IlvMapLineString, IlvMapArcString, and IlvMapCurveString.
|
pure virtual |
Returns the end point of the last segment.
(0, 0) is returned. Implements IlvMapSegment.
Implemented in IlvMapLineString, IlvMapArcString, and IlvMapCurveString.
|
pure virtual |
Returns the segment at a given index.
| index | The index of the segment to be retrieved. index must have a value between 0 and getSegmentCount()-1. |
IlvMapSegment object that should not be modified nor deleted by the user. The returned IlvMapSegment is volatile: it may be modified or deleted by the IlvMapSegmentString itself after an other call to this function, or after any modification. Implemented in IlvMapLineString, IlvMapArcString, and IlvMapCurveString.
|
pure virtual |
Returns the number of segments contained in the string.
Implemented in IlvMapLineString, IlvMapArcString, and IlvMapCurveString.
|
pure virtual |
Returns the start point of the first segment, if it exists, otherwise, it returns an IlvCoordinate set to (0,0).
Implements IlvMapSegment.
Implemented in IlvMapLineString, IlvMapArcString, and IlvMapCurveString.
|
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.
|
pure virtual |
Sets the end point of the last segment if it exists.
If the end point of the last segment does not exists, this method does nothing.
| end | The end point. |
Implements IlvMapSegment.
Implemented in IlvMapLineString, IlvMapArcString, and IlvMapCurveString.
|
pure virtual |
Sets the start point of the first segment.
| start | The start point. |
Implements IlvMapSegment.
Implemented in IlvMapLineString, IlvMapArcString, and IlvMapCurveString.
