default

Default constructor.

Member Function Documentation

void SFCGAL::detail::SegmentStore::addSegment ( const Segment &  segment )

inline

Add a segment to the store.

Parameters

segment

The segment to add

auto SFCGAL::detail::SegmentStore::createPoint ( double  x, double  y, CoordinateType  dimension  ) const -> Point

inline

Create a point with interpolated Z and M values.

Parameters

x	X-coordinate of the point
y	Y-coordinate of the point
dimension	The coordinate type for the point

Returns

Point with interpolated Z and M values

auto SFCGAL::detail::SegmentStore::extractSegments ( const LineString &  lineString ) -> void

inline

Extract segments from a LineString for interpolation.

Parameters

lineString

The linestring to extract segments from

auto SFCGAL::detail::SegmentStore::extractSegments ( const Polygon &  polygon ) -> void

inline

Extract segments from a Polygon for interpolation.

Parameters

polygon

The polygon to extract segments from

auto SFCGAL::detail::SegmentStore::extractSegments ( const Geometry &  geometry ) -> void

inline

Extract segments from all geometry types.

Parameters

geometry

The geometry to extract segments from

auto SFCGAL::detail::SegmentStore::findNearestSegment ( double  x, double  y  ) const -> Segment

inline

Find the nearest segment to a point.

Parameters

x	X-coordinate of the point
y	Y-coordinate of the point

Returns

The nearest segment to the given point

auto SFCGAL::detail::SegmentStore::hasM ( ) const -> bool

inline

Check if store contains segments with M values.

Returns

True if any segment has M values

auto SFCGAL::detail::SegmentStore::hasZ ( ) const -> bool

inline

Check if store contains segments with Z coordinates.

Returns

True if any segment has Z coordinates

auto SFCGAL::detail::SegmentStore::interpolateZM ( double  x, double  y  ) const -> std::tuple<double, double>

inline

Interpolate Z and M values for a point.

Parameters

x	X-coordinate of the point
y	Y-coordinate of the point

Returns

Tuple with interpolated (z, m) values, NaN if not applicable
