Return the Well-Known Text (WKT) representation of the geometry/geography with SRID metadata. Returns True if and only if no points of B lie in the exterior of A, and at least one point of the interior of B lies in the interior of A.

Each of the geometry types can also be a (typed) empty set, containing zero coordinates (for POINT the standard is not clear how to represent the empty geometry). The way this is printed is called well-known text, and is part of the standards.
