Detailed Description

Optimized implementation of the "intersects" spatial predicate for cases where one Geometry is a rectangle.

This class works for all input geometries, including GeometryCollections.

As a further optimization, this class can be used to test many geometries against a single rectangle in a slightly more efficient way.

Constructor & Destructor Documentation

RectangleIntersects()

geos::operation::predicate::RectangleIntersects::RectangleIntersects ( const geom::Polygon &  newRect )

inline

Create a new intersects computer for a rectangle.

Parameters

newRect

a rectangular geometry

Member Function Documentation

intersects()

static bool geos::operation::predicate::RectangleIntersects::intersects ( const geom::Polygon &  rectangle, const geom::Geometry &  b  )

inlinestatic

Tests whether a rectangle intersects a given geometry.

Parameters

rectangle	a rectangular Polygon
b	a Geometry of any type

Returns

true if the geometries intersect
