mountTopology()

te::gm::GeometryPtr te::gm::AbstractValidator::mountTopology ( const te::gm::GeometryVector &  vecOuterRings, const te::gm::GeometryVector &  vecInnerRings  ) const

protected

This function recreates the rings topology of a polygon, distributing the given inner rings among all the given outer rings.

Parameters

vecOuterRings	A vector containing all the outer rings
vecInnerRings	A vector containing all the inner rings

Returns

The geometry with the ring topology fixed

setPrecision()

virtual void te::gm::AbstractValidator::setPrecision ( double  precision )

virtual

When appliable, sets the precision to be used in the validation.

Parameters

precision

When appliable, the precision to be used in the validation

validate() [1/2]

virtual te::gm::GeometryPtr te::gm::AbstractValidator::validate ( const te::gm::Geometry *  geometry ) const

virtual

Validates a geometry.

Parameters

geometry

Returns

The valdiated result geometry

validate() [2/2]

virtual te::gm::GeometryPtr te::gm::AbstractValidator::validate ( const te::gm::Geometry *  geometry, bool &  wasChanged  ) const

virtual

Validates a geometry, an returns additional variable to inform if the geometry has been changed or not.

Parameters

geometry	The input geometry to be validate
wasChanged	output param. TRUE if the geometry has been changed. FALSE otherwise

Returns

The valdiated result geometry

Reimplemented in te::gm::MergeCoordinates, and te::gm::AddProjectedCoordinates.

validateCollection()

virtual te::gm::GeometryPtr te::gm::AbstractValidator::validateCollection ( const te::gm::GeometryCollection *  collection, bool &  wasChanged  ) const

protectedvirtual

Validates a geometry collection, an returns additional variable to inform if the geometry has been changed or not.

Parameters

geometry	The input geometry collection to be validate
wasChanged	output param. TRUE if the geometry has been changed. FALSE otherwise

Parameters

geometry	The input line to be validate
wasChanged	output param. TRUE if the geometry has been changed. FALSE otherwise

Returns

The valdiated result line

Implemented in te::gm::RemoveCollapsedSegments, te::gm::MergeCoordinates, te::gm::FixRepeatedCoordinates, te::gm::FixOrientation, te::gm::FixNoding, and te::gm::AddProjectedCoordinates.

virtual te::gm::GeometryPtr te::gm::AbstractValidator::validatePolygon ( const te::gm::Polygon *  polygon, bool &  wasChanged  ) const

protectedvirtual

Validates a polygon, an returns additional variable to inform if the geometry has been changed or not.

Parameters

geometry	The input polygon to be validate
wasChanged	output param. TRUE if the geometry has been changed. FALSE otherwise

Returns
