Member Function Documentation

intersects() [1/2]

bool geos::geom::prep::PreparedPolygonIntersects::intersects

(

const geom::Geometry *

geom

)

Tests whether this PreparedPolygon intersects a given geometry.

Parameters

geom	the test geometry

Returns

true if the test geometry intersects

inlinestatic

Computes the intersects predicate between a PreparedPolygon and a Geometry.

Parameters

prep	the prepared polygon
geom	a test geometry

Returns

true if the polygon intersects the geometry
