Detailed Description

A base class for PreparedGeometry subclasses.

Contains default implementations for methods, which simply delegate to the equivalent Geometry methods. This class may be used as a "no-op" class for Geometry types which do not have a corresponding PreparedGeometry implementation.

Parameters

g	a Geometry

Returns: true if g is contained in this envelope

◆ envelopesIntersect()

bool geos::geom::prep::BasicPreparedGeometry::envelopesIntersect ( const geom::Geometry * g ) const

protected

Determines whether a Geometry g interacts with this geometry by testing the geometry envelopes.

Parameters
