ReQL command: intersects
Command syntax
sequence.intersects(geometry) → sequence geometry.intersects(geometry) → bool r.intersects(sequence, geometry) → sequence r.intersects(geometry, geometry) → bool
Description
Tests whether two geometry objects intersect with one another. When applied to a sequence of geometry objects, intersects
acts as a filter, returning a sequence of objects from the sequence that intersect with the argument.
Example: Is point2
within a 2000-meter circle around point1
?
import com.rethinkdb.gen.ast.Point;
Point point1 = r.point(-117.220406,32.719464);
Point point2 = r.point(-117.206201,32.725186);
r.circle(point1, 2000).intersects(point2).run(conn);
// Result:
true
Example: Which of the locations in a list of parks intersect a given circle?
r.table("parks").g("area")
.intersects(r.circle(r.array(-117.220406, 32.719464), 10).optArg("unit", "mi"))
.run(conn);
The
intersects
command cannot take advantage of a geospatial secondary index. If you’re working with large data sets, you should consider using an index and the getIntersecting command instead ofintersects
