&&(geometry,box2df) — Returns TRUE
if a geometry's (cached) 2D bounding box intersects a 2D float precision bounding box (BOX2DF).
boolean &&(
geometry
A
,
box2df
B
)
;
The &&
operator returns TRUE
if the cached 2D bounding box of geometry A intersects the 2D bounding box B, using float precision. This means that if B 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. |
