#1026: && vs. &&& what's the difference
---------------------+------------------------------------------------------
Reporter: robe | Owner: pramsey
Type: defect | Status: new
Priority: medium | Milestone: PostGIS 2.0.0
Component: postgis | Version: trunk
Keywords: |
---------------------+------------------------------------------------------
These seem to be exactly the same in my installs shouldn't one be a 2d
interacts check and the other a 3D interacts check?
The definitions look the same and when testing they seem to give the same
answers with 3D geometries even in cases where I expect &&& to return
false and && to return true
e.g. both have:
{{{
CREATE OPERATOR &&&(
PROCEDURE = geometry_overlaps,
LEFTARG = geometry,
RIGHTARG = geometry,
COMMUTATOR = &&&,
RESTRICT = contsel,
JOIN = contjoinsel);
CREATE OPERATOR &&(
PROCEDURE = geometry_overlaps,
LEFTARG = geometry,
RIGHTARG = geometry,
COMMUTATOR = &&,
RESTRICT = contsel,
JOIN = contjoinsel);
}}}
