Geometry
classes support the concept of applying a coordinate filter to every coordinate in the Geometry
.
A coordinate filter can either record information about each coordinate or change the coordinate in some way. Coordinate filters implement the interface CoordinateFilter
. (CoordinateFilter
is an example of the Gang-of-Four Visitor pattern). Coordinate filters can be used to implement such things as coordinate transformations, centroid and envelope computation, and many other functions.
TODO: provide geom::CoordinateInspector and geom::CoordinateMutator instead of having the two versions of filter_rw and filter_ro
