ClipGeometry()

static te::gm::Geometry * te::gm::SafeOverlay::ClipGeometry ( const te::gm::Geometry *  geometry, const te::gm::Envelope &  envelope  )

static

Tries to make the difference. If an exception is thrown, it tries to make the geometry valid and retry again.

Difference()

static te::gm::GeometryPtr te::gm::SafeOverlay::Difference ( const te::gm::Geometry *  g1, const te::gm::Geometry *  g2  )

static

Tries to make the intersection. If an exception is thrown, it tries to make the geometry valid and retry again.

Intersection()

static te::gm::GeometryPtr te::gm::SafeOverlay::Intersection ( const te::gm::Geometry *  g1, const te::gm::Geometry *  g2  )

static

Tries to make the geometry pair valid. If it is unable to do that, it will throw an exception.

MakeValid()
