java.lang.Object com.vividsolutions.jts.precision.GeometryPrecisionReducer
public class GeometryPrecisionReducer
Reduces the precision of a Geometry
according to the supplied PrecisionModel
,
ensuring that the result is topologically valid.

static Geometry |
reduce(Geometry g,
PrecisionModel precModel)
Convenience method for doing precision reduction on a single geometry, with collapses removed and keeping the geometry precision model the same, and preserving polygonal topology. |
static Geometry |
reducePointwise(Geometry g,
PrecisionModel precModel)
Convenience method for doing pointwise precision reduction on a single geometry, with collapses removed and keeping the geometry precision model the same, but NOT preserving valid polygonal topology. |
void |
setChangePrecisionModel(boolean changePrecisionModel)
Sets whether the PrecisionModel of the new reduced Geometry
will be changed to be the PrecisionModel supplied to
specify the precision reduction. |
void |
setPointwise(boolean isPointwise)
Sets whether the precision reduction will be done in pointwise fashion only. |
void |
setRemoveCollapsedComponents(boolean removeCollapsed)
Sets whether the reduction will result in collapsed components being removed completely, or simply being collapsed to an (invalid) Geometry of the same type. |

specify the precision reduction.
The default is to not change the precision model

the precision model of the created Geometry will be the
the precisionModel supplied in the constructor.public void setPointwise(boolean isPointwise)
