Module RingFuncs 

Ring functions

Functions for working directly with the tg_ring type.

There are no direct spatial predicates for tg_ring. If you want to perform operations like “intersects” or “covers” then you must upcast the ring to a tg_geom, like such:

tg_geom_intersects((struct tg_geom*)ring, geom);
