bool te::gm::FixGeometryTopology::closeGeometryRing ( const te::gm::Geometry &  geometry,
TopologyValidationError  topologyError 
)
staticprivate

This function closes an opened geometry ring.

Parameters
geometryToFixInput Geometry to fix.
topologyErrorIf any error occurs, TopologyValidationError struct is populated with error message and geometry coordinate.
Returns
True, if the the function was executed successfully and the geometry was fixed correctly.
Note
This function is only used for Geometries of Polygon and MultiPolygon types.
