Detailed Description

Visitor interface for non-const Geometry types.

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

Constructor & Destructor Documentation

SFCGAL::GeometryVisitor::~GeometryVisitor ( )

virtualdefault

Default destructor for GeometryVisitor.

Defaulted destructor provided for proper destruction of derived visitor instances.

Member Function Documentation

void SFCGAL::GeometryVisitor::visit ( Geometry & geometry )

virtual

Apply this visitor to a generic Geometry reference.

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

Parameters

geometry The geometry to visit.

virtual void SFCGAL::GeometryVisitor::visit ( Point & geometry )

pure virtual

Visit a Point geometry.

Parameters

geometry The Point geometry to visit

Implemented in SFCGAL::Transform, and SFCGAL::detail::ForceValidityVisitor.

virtual void SFCGAL::GeometryVisitor::visit ( LineString & geometry )

pure virtual

Visit a LineString geometry.

Parameters

geometry The LineString geometry to visit

Implemented in SFCGAL::Transform, and SFCGAL::detail::ForceValidityVisitor.

virtual void SFCGAL::GeometryVisitor::visit ( Polygon & geometry )

pure virtual

Visit a Polygon geometry.

Parameters

geometry The Polygon geometry to visit

Implemented in SFCGAL::Transform, SFCGAL::transform::ForceOrderPoints, SFCGAL::transform::ForceZOrderPoints, and SFCGAL::detail::ForceValidityVisitor.

virtual void SFCGAL::GeometryVisitor::visit ( Triangle & geometry )

pure virtual

Visit a Triangle geometry.

Parameters

geometry The Triangle geometry to visit

Implemented in SFCGAL::Transform, SFCGAL::detail::ForceValidityVisitor, SFCGAL::transform::ForceOrderPoints, and SFCGAL::transform::ForceZOrderPoints.

virtual void SFCGAL::GeometryVisitor::visit ( Solid & geometry )

pure virtual

Visit a Solid geometry.

Parameters

geometry The Solid geometry to visit

Implemented in SFCGAL::Transform, and SFCGAL::detail::ForceValidityVisitor.

virtual void SFCGAL::GeometryVisitor::visit ( MultiPoint & geometry )

pure virtual

Visit a MultiPoint geometry.

Parameters

geometry The MultiPoint geometry to visit

Implemented in SFCGAL::Transform, and SFCGAL::detail::ForceValidityVisitor.

virtual void SFCGAL::GeometryVisitor::visit ( MultiLineString & geometry )

pure virtual

Visit a MultiLineString geometry.

Parameters

geometry The MultiLineString geometry to visit

Implemented in SFCGAL::Transform, and SFCGAL::detail::ForceValidityVisitor.

virtual void SFCGAL::GeometryVisitor::visit ( MultiPolygon & geometry )

pure virtual

Visit a MultiPolygon geometry.

Parameters

geometry The MultiPolygon geometry to visit

Implemented in SFCGAL::Transform, and SFCGAL::detail::ForceValidityVisitor.

virtual void SFCGAL::GeometryVisitor::visit ( MultiSolid & geometry )

pure virtual

Visit a MultiSolid geometry.

Parameters

geometry The MultiSolid geometry to visit

Implemented in SFCGAL::Transform, and SFCGAL::detail::ForceValidityVisitor.

virtual void SFCGAL::GeometryVisitor::visit ( GeometryCollection & geometry )

pure virtual

Visit a GeometryCollection geometry.

Parameters

geometry The GeometryCollection geometry to visit

Implemented in SFCGAL::Transform, and SFCGAL::detail::ForceValidityVisitor.

virtual void SFCGAL::GeometryVisitor::visit ( PolyhedralSurface & geometry )

pure virtual

Visit a PolyhedralSurface geometry.

Parameters

geometry The PolyhedralSurface geometry to visit

Implemented in SFCGAL::Transform, and SFCGAL::detail::ForceValidityVisitor.

virtual void SFCGAL::GeometryVisitor::visit ( TriangulatedSurface & geometry )

pure virtual

Visit a TriangulatedSurface geometry.

Parameters

geometry The TriangulatedSurface geometry to visit

Implemented in SFCGAL::Transform, and SFCGAL::detail::ForceValidityVisitor.

void SFCGAL::GeometryVisitor::visit ( NURBSCurve & geometry )

virtual

Visit a NURBSCurve geometry.

ABI-compatible default visitor for NURBSCurve.

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

Parameters

geometry The NURBSCurve to visit.

This default implementation does not process the NURBSCurve and exists only to preserve ABI compatibility. It throws std::runtime_error; derived visitors should override this method to provide proper NURBS handling (for example, by converting the NURBSCurve to a LineString and visiting it).

Exceptions

std::runtime_error Always thrown to indicate the NURBSCurve visitor is not implemented.

Reimplemented in SFCGAL::Transform, and SFCGAL::detail::ForceValidityVisitor.
