Detailed Description

Visitor interface for const Geometry types.

Implementations should provide behavior for each concrete const geometry type via the type-specific visit overloads. The destructor is virtual to allow safe subclass destruction.

Constructor & Destructor Documentation

SFCGAL::ConstGeometryVisitor::~ConstGeometryVisitor ( )

virtualdefault

Default destructor for ConstGeometryVisitor.

Defaulted destructor provided for proper destruction of derived visitor instances.

Member Function Documentation

void SFCGAL::ConstGeometryVisitor::visit ( const Geometry & geometry )

virtual

Apply this visitor to a generic const Geometry reference.

Concrete visitors can override this to provide a common fallback for any const Geometry not handled by the type-specific overloads.

Parameters

geometry The const geometry to visit.

virtual void SFCGAL::ConstGeometryVisitor::visit ( const Point & geometry )

pure virtual

Visit a const Point geometry.

Parameters

geometry The const Point geometry to visit

Implemented in SFCGAL::algorithm::BoundaryVisitor, SFCGAL::detail::EnvelopeVisitor, and SFCGAL::detail::GetPointsVisitor.

virtual void SFCGAL::ConstGeometryVisitor::visit ( const LineString & geometry )

pure virtual

Visit a const LineString geometry.

Parameters

geometry The const LineString geometry to visit

Implemented in SFCGAL::algorithm::BoundaryVisitor, SFCGAL::detail::EnvelopeVisitor, and SFCGAL::detail::GetPointsVisitor.

virtual void SFCGAL::ConstGeometryVisitor::visit ( const Polygon & geometry )

pure virtual

Visit a const Polygon geometry.

Parameters

geometry The const Polygon geometry to visit

Implemented in SFCGAL::algorithm::BoundaryVisitor, SFCGAL::detail::EnvelopeVisitor, and SFCGAL::detail::GetPointsVisitor.

virtual void SFCGAL::ConstGeometryVisitor::visit ( const Triangle & geometry )

pure virtual

Visit a const Triangle geometry.

Parameters

geometry The const Triangle geometry to visit

Implemented in SFCGAL::algorithm::BoundaryVisitor, SFCGAL::detail::EnvelopeVisitor, and SFCGAL::detail::GetPointsVisitor.

virtual void SFCGAL::ConstGeometryVisitor::visit ( const Solid & geometry )

pure virtual

Visit a const Solid geometry.

Parameters

geometry The const Solid geometry to visit

Implemented in SFCGAL::algorithm::BoundaryVisitor, SFCGAL::detail::EnvelopeVisitor, and SFCGAL::detail::GetPointsVisitor.

virtual void SFCGAL::ConstGeometryVisitor::visit ( const MultiPoint & geometry )

pure virtual

Visit a const MultiPoint geometry.

Parameters

geometry The const MultiPoint geometry to visit

Implemented in SFCGAL::algorithm::BoundaryVisitor, SFCGAL::detail::EnvelopeVisitor, and SFCGAL::detail::GetPointsVisitor.

virtual void SFCGAL::ConstGeometryVisitor::visit ( const MultiLineString & geometry )

pure virtual

Visit a const MultiLineString geometry.

Parameters

geometry The const MultiLineString geometry to visit

Implemented in SFCGAL::algorithm::BoundaryVisitor, SFCGAL::detail::EnvelopeVisitor, and SFCGAL::detail::GetPointsVisitor.

virtual void SFCGAL::ConstGeometryVisitor::visit ( const MultiPolygon & geometry )

pure virtual

Visit a const MultiPolygon geometry.

Parameters

geometry The const MultiPolygon geometry to visit

Implemented in SFCGAL::algorithm::BoundaryVisitor, SFCGAL::detail::EnvelopeVisitor, and SFCGAL::detail::GetPointsVisitor.

virtual void SFCGAL::ConstGeometryVisitor::visit ( const MultiSolid & geometry )

pure virtual

Visit a const MultiSolid geometry.

Parameters

geometry The const MultiSolid geometry to visit

Implemented in SFCGAL::algorithm::BoundaryVisitor, SFCGAL::detail::EnvelopeVisitor, and SFCGAL::detail::GetPointsVisitor.

virtual void SFCGAL::ConstGeometryVisitor::visit ( const GeometryCollection & geometry )

pure virtual

Visit a const GeometryCollection geometry.

Parameters

geometry The const GeometryCollection geometry to visit

Implemented in SFCGAL::algorithm::BoundaryVisitor, SFCGAL::detail::EnvelopeVisitor, and SFCGAL::detail::GetPointsVisitor.

virtual void SFCGAL::ConstGeometryVisitor::visit ( const PolyhedralSurface & geometry )

pure virtual

Visit a const PolyhedralSurface geometry.

Parameters

geometry The const PolyhedralSurface geometry to visit

Implemented in SFCGAL::algorithm::BoundaryVisitor, SFCGAL::detail::EnvelopeVisitor, and SFCGAL::detail::GetPointsVisitor.

virtual void SFCGAL::ConstGeometryVisitor::visit ( const TriangulatedSurface & geometry )

pure virtual

Visit a const TriangulatedSurface geometry.

Parameters

geometry The const TriangulatedSurface geometry to visit

Implemented in SFCGAL::algorithm::BoundaryVisitor, SFCGAL::detail::EnvelopeVisitor, and SFCGAL::detail::GetPointsVisitor.

void SFCGAL::ConstGeometryVisitor::visit ( const NURBSCurve & geometry )

virtual

Visit a const NURBSCurve geometry.

Default const visitor for NURBSCurve.

Default implementation provides no-op; override to handle const NURBSCurve.

Parameters

geometry The const NURBSCurve to visit.

This ABI-compatible default implementation does not handle NURBSCurve directly. It throws std::runtime_error to force derived visitors to provide proper NURBS handling (the intended fallback behavior would be to convert the curve to a LineString and visit that).

Exceptions

std::runtime_error Always thrown with message "NURBSCurve const visitor not implemented".

Reimplemented in SFCGAL::algorithm::BoundaryVisitor, SFCGAL::detail::EnvelopeVisitor, and SFCGAL::detail::GetPointsVisitor.
