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.

Authors:: Martin Davis

public BasicPreparedGeometry(Geometry geom)

public Geometry getGeometry()

public List getRepresentativePoints()

Gets the list of representative points for this geometry. One vertex is included for every component of the geometry (i.e. including one for every ring of polygonal geometries). Do not modify the returned list!

Returns:: a List of Coordinate

public boolean isAnyTargetComponentInTest(Geometry testGeom)

Tests whether any representative of the target geometry intersects the test geometry. This is useful in A/A, A/L, A/P, L/P, and P/P cases.

Parameters:: testGeom - testGeom the test geometry

Returns:: true if any component intersects the areal test geometry

protected boolean envelopesIntersect(Geometry g)

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

Parameters:: g - g a Geometry

Returns:: true if the envelopes intersect

protected boolean envelopeCovers(Geometry g)

Determines whether the envelope of this geometry covers the Geometry g.

Parameters:: g - g a Geometry

Returns:: true if g is contained in this envelope
