&&(box2df,geometry) — Returns TRUE
if a 2D float precision bounding box (BOX2DF) intersects a geometry's (cached) 2D bounding box.
boolean &&(
box2df A , geometry B )
;
The &&
operator returns TRUE
if the 2D bounding box A intersects the cached 2D bounding box of geometry B, using float precision. This means that if A is a (double precision) box2d, it will be internally converted to a float precision 2D bounding box (BOX2DF)
This operand is intended to be used internally by BRIN indexes, more than by users. |
