public interface GeometryComponentFilter
Geometry
classes support the concept of applying
a GeometryComponentFilter
filter to the Geometry
.
The filter is applied to every component of the Geometry
which is itself a Geometry
and which does not itself contain any components.
(For instance, all the LinearRing
s in Polygon
s are visited,
but in a MultiPolygon
the Polygon
s themselves are not visited.)
Thus the only classes of Geometry which must be
handled as arguments to filter(org.locationtech.jts.geom.Geometry)
are LineString
s, LinearRing
s and Point
s.
A GeometryComponentFilter
filter can either
record information about the Geometry
or change the Geometry
in some way.
GeometryComponentFilter
is an example of the Gang-of-Four Visitor pattern.
