ReQL command: includes
Command syntax
sequence.includes(geometry) → sequence geometry.includes(geometry) → bool
Description
Tests whether a geometry object is completely contained within another. When applied to a sequence of geometry objects, includes
acts as a filter, returning a sequence of objects from the sequence that include the argument.
Example: Is a point included within a 2000-meter circle?
Object point1 = r.point(-117.220406,32.719464);
Object point2 = r.point(-117.206201,32.725186);
r.circle(point1, 2000).includes(point2).run(conn);
// Result:
true
Example: Which of the locations in a list of parks include a given circle?
import com.rethinkdb.gen.ast.Circle;
Circle circle1 = r.circle(r.array(-117.220406, 32.719464), 10)
.optArg("unit", "mi");
r.table("parks").g("area").includes(circle1).run(conn);
The
includes
command cannot take advantage of a geospatial secondary index. If you’re working with large data sets, consider using an index and getIntersecting beforeincludes
to narrow down the initial result set.
Example: Rewrite the previous example with getIntersecting
.
Circle circle1 = r.circle(r.array(-117.220406, 32.719464), 10)
.optArg("unit", "mi");
r.table("parks").getIntersecting(circle1)
.optArg("index", "area").g("area")
.includes(circle1).run(conn);
