Family operator strategies
| Operator overload | Strategy | Purpose | Ordering family | Membership scope | Source description |
|---|---|---|---|---|---|
| |>>(point,point) | 11 | search | Family member | is above | |
| >^(point,point) | 30 | search | Family member | deprecated, use |>> instead | |
| <<(point,point) | 1 | search | Family member | is left of | |
| >>(point,point) | 5 | search | Family member | is right of | |
| <<|(point,point) | 10 | search | Family member | is below | |
| <^(point,point) | 29 | search | Family member | deprecated, use <<| instead | |
| ~=(point,point) | 6 | search | Family member | same as | |
| <->(point,point) | 15 | ordering | float_ops | Family member | distance between |
| <@(point,box) | 28 | search | Family member | point inside box | |
| <@(point,polygon) | 48 | search | Family member | is contained by | |
