<< <@ <^ >> >^ ~= |
range_ops |
any range type | && &< &> -|- << <@ = >> @> |
box_ops |

Of the two operator classes for type point
, quad_point_ops
is the default. kd_point_ops
supports the same operators but uses a different index data structure that may offer better performance in some applications.
