org.geomajas.gwt.client.spatial.geometry.GeometryFactory.createLinearRing()
Create a new {@link LinearRing}, given an array of coordinates. @param coordinates An array of {@link Coordinate} objects. This function checks if the array is closed, and does soitself if needed. @return Returns a {@link LinearRing} object.
