Examples of org.geotools.geometry.jts.GeometryBuilder

org.geotools.geometry.jts.GeometryBuilder
A builder for {@link Geometry} objects. Primarily intended tosupport fluent programming in test code.
Features include:
- Both 2D and 3D coordinate dimensions are supported (assuming the provided {@link CoordinateSequenceFactory} supports them)
- Sequences of ordinate values can be supplied in a number of ways
- Rings do not need to be explicitly closed; a closing point will be supplied if needed
- Empty geometries of all types can be created
- Composite geometries are validated to ensure they have a consistent GeometryFactory and coordinate sequence dimension
  Examples of intended usage are:
```
 GeometryBuilder gb = new GeometryBuilder(geomFact); LineString line = gb.linestring(1,2, 3,4); Polygon poly = gb.polygon(0,0, 0,1, 1,1, 1,0); Polygon box = gb.box(0,0, 1,1); Polygon hexagon = gb.circle(0,0, 1,1, 6); Polygon polyhole = gb.polygon(gb.linearring(0,0, 0,10, 10,10, 10,0), gb.linearring(1,1, 1,9, 9,9, 9,1)) 
```
