fixOverlaps() [1/2]

static te::gm::GeometryVector te::vp::OverlapFixer::fixOverlaps ( std::vector< GeometryInfoOverlap * > &  vecGeometries )

staticprotected

Internal method to fix the existing overlaps of the polygons ou multipolygons from the given vecGeometries vector.

Parameters

vecGeometries

The input geometries to be analysed

Returns

A vector containing the fixed geometries

fixOverlaps() [2/2]

static void te::vp::OverlapFixer::fixOverlaps ( std::vector< GeometryInfoOverlap * > &  vecGeometries, const te::gm::GeometryVector &  vecFragments  )

staticprotected

Internal method to fix the existing overlaps of the polygons ou multipolygons from the given vecGeometries vector considering the given intersection fragments.

Parameters

vecGeometries	The input geometries to be fixed
vecFragments	The intersection fragments to be used to fix the geometries

hasOverlaps()

static bool te::vp::OverlapFixer::hasOverlaps ( const te::gm::Geometry *  geometryA, const te::gm::Geometry *  geometryB  )
