void geos::precision::CommonBitsRemover::add ( const geom::Geometry geom)

Add a geometry to the set of geometries whose common bits are being computed. After this method has executed the common coordinate reflects the common bits of all added geometries.

Parameters
geoma Geometry to test for common bits

geom::Geometry* geos::precision::CommonBitsRemover::addCommonBits ( geom::Geometry geom)

Adds the common coordinate bits back into a Geometry. The coordinates of the Geometry are changed.

Parameters
geomthe Geometry to which to add the common coordinate bits
Returns
the shifted Geometry
