geos::geom::Envelope
An Envelope defines a rectangulare region of the 2D coordinate plane.
Definition Envelope.h:59
geos::geom::Envelope::intersects
static bool intersects(const CoordinateXY &p1, const CoordinateXY &p2, const CoordinateXY &q)
Test the point q to see whether it intersects the Envelope defined by p1-p2.
geos::geom::Geometry
Basic implementation of Geometry, constructed and destructed by GeometryFactory.
Definition Geometry.h:196
geos::geom::Geometry::getEnvelopeInternal
virtual const Envelope * getEnvelopeInternal() const =0
Returns the minimum and maximum x and y values in this Geometry, or a null Envelope if this Geometry ...
