Examples of com.vividsolutions.jts.geom.Geometry.apply()

com.vividsolutions.jts.geom.Geometry.apply()
Performs an operation with or on this Geometry's coordinates. If this method modifies any coordinate values, {@link #geometryChanged} must be called to update the geometry state. Note that you cannot use this method to modify this Geometry if its underlying CoordinateSequence's #get method returns a copy of the Coordinate, rather than the actual Coordinate stored (if it even stores Coordinate objects at all). @param filter the filter to apply to this Geometry'scoordinates
