java.lang.Objectcom.vividsolutions.jts.precision.SimpleGeometryPrecisionReducer
public class SimpleGeometryPrecisionReducer
Reduces the precision of a Geometry
according to the supplied PrecisionModel
, without
attempting to preserve valid topology.
The topology of the resulting geometry may be invalid if topological collapse occurs due to coordinates being shifted. It is up to the client to check this and handle it if necessary. Collapses may not matter for some uses. An example is simplifying the input to the buffer algorithm. The buffer algorithm does not depend on the validity of the input 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. |
void |
setChangePrecisionModel(boolean changePrecisionModel)
Sets whether the PrecisionModel of the new reduced Geometry
will be changed to be the PrecisionModel supplied to
specify the reduction. |
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. |
