◆ Overlaps()

bool RING_2D::Overlaps ( const BBOX_2D & aBBox ) const

overridevirtual

Test if the box overlaps the object.

Conformance Implements the Overlaps function from the OGC Simple Feature Specification at http://www.opengeospatial.org/standards/sfa. a.Overlaps(b) ⇔ ( dim(I(a)) = dim(I(b)) = dim(I(a) ∩ I(b))) ∧ (a ∩ b ≠ a) ∧ (a ∩ b ≠ b) It means that the result dimension of an overlap is the same dimensions of the bounding box (so the overlap cannot be a point or a line) and one of the boxes cannot full contain the other box.

Parameters

aBBox is the bounding box to test.

Returns: true if the BBox intersects the object or is inside it.

Implements OBJECT_2D.

{
 // NOT IMPLEMENTED, why?
 return false;
