This implementation fo the IlvMapSegmentString
class supports any sequence of IlvMapSegment
.
The instances of this class can be rendered by an IlvDefaultFeatureRenderer
or by an IlvDefaultCurveRenderer
. Library: ilvmaps
IlvMapCurveString::IlvMapCurveString | ( | ) |
Constructor.
Initializes an instance of the class.
IlvMapCurveString::IlvMapCurveString | ( | const IlvMapCurveString & | source | ) |
Creates a segment string by copying an existing one.
source | The source segment string. |
|
virtual |
Returns a copy of the object.
IlvMapGeometry
that must be deleted by the user. Implements IlvMapSegmentString.
|
virtual |
Returns the IlvClassInfo
of the instance.
IlvClassInfo
that should not be modified nor deleted. Implements IlvMapSegmentString.
|
virtual |
Returns the end point of the last segment, if it exists, otherwise, it returns an IlvCoordinate
set to (0,0).
Implements IlvMapSegmentString.
|
virtual |
Returns the number of intersections between an horizontal half line defined by its right extremity point and the segment. This function is used for point inclusion tests of IlvMapRing
.
point | The point at the right extremity of the horizontal half line. |
1
if the point is on the segment, 2
if the point is not on the segment. If the point is on the segment where the tangent is not horizontal, the intersection should not be counted. Implements IlvMapSegment.
|
virtual |
Returns the segment of index 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. This means that it may be modified or deleted by the IlvMapSegmentString
itself after an other call to this function, or after any modification. Implements IlvMapSegmentString.
|
virtual |
Returns the number of segments contained in the string.
Implements IlvMapSegmentString.
|
virtual |
Returns the start point of the first segment, if it exists, otherwise, it returns an IlvCoordinate
set to (0,0).
Implements IlvMapSegmentString.
void IlvMapCurveString::joinSegment | ( | IlvMapSegment * | segment | ) |
Joins a segment at the end of the string.
The last point of the preceding segment is moved to fit the starting point of the segment given as argument. In this operation, the IlvMapCurveString
object becomes owner of segment.
segment | The segment to be joined. |
|
virtual |
Sets the end point of the last segment if it exists.
Otherwise, it does nothing.
end | The end point. |
Implements IlvMapSegmentString.
|
virtual |
Sets the start point of the first segment.
start | The start point. |
Implements IlvMapSegmentString.
