#include <cartotype_path.h>
An iterator to traverse a path. Limitation: for the moment it works with straight lines only; it treats all points as on-curve points.
◆ PathIterator()
| CartoTypeCore::PathIterator::PathIterator |
( |
const MPath & |
aPath | ) |
|
Creates a path iterator over aPath and sets it to the start of aPath.
◆ ContourByIndex()
| ContourView CartoTypeCore::PathIterator::ContourByIndex |
( |
| ) |
const |
|
inline |
Returns the current contour.
◆ ContourIndex()
| size_t CartoTypeCore::PathIterator::ContourIndex |
( |
| ) |
const |
|
inline |
Returns the current contour index.
◆ Direction()
| double CartoTypeCore::PathIterator::Direction |
( |
| ) |
const |
|
inline |
Returns the current direction in radians, clockwise from straight up, as an angle on the map, not a geodetic azimuth.
◆ Forward()
| bool CartoTypeCore::PathIterator::Forward |
( |
double |
aDistance | ) |
|
Moves forwards by aDistance. Returns false if already at the end of the path, true if not.
◆ LineIndex()
| size_t CartoTypeCore::PathIterator::LineIndex |
( |
| ) |
const |
|
inline |
Returns the current line index.
◆ MoveToNearestPoint()
| void CartoTypeCore::PathIterator::MoveToNearestPoint |
( |
const PointFP & |
aPoint | ) |
|
Set the path iterator's current position to the nearest point to aPoint.
◆ NextContour()
| bool CartoTypeCore::PathIterator::NextContour |
( |
| ) |
|
Moves to the start of the next contour of the path. Returns true if the move was possible.
◆ Position()
| const Point & CartoTypeCore::PathIterator::Position |
( |
| ) |
const |
|
inline |
Returns the current position.
◆ PositionOnLine()
| double CartoTypeCore::PathIterator::PositionOnLine |
( |
| ) |
const |
|
inline |
Returns the current position along the current line.
