public class SimpleGeometryPrecisionReducer extends java.lang.Object
Deprecated.use GeometryPrecisionReducerReduces the precision of the coordinates of aGeometry
according to the suppliedPrecisionModel
, without attempting to preserve valid topology.In the case of
Polygonal
geometries, 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.- Version:

reduce
public static Geometry reduce(Geometry g, PrecisionModel precModel)
Deprecated.Convenience method for doing precision reduction on a single geometry, with collapses removed and keeping the geometry precision model the same.- Parameters:
g
-precModel
-- Returns:
- the reduced geometry
-
setRemoveCollapsedComponents
public void setRemoveCollapsedComponents(boolean removeCollapsed)
Deprecated.Sets whether the reduction will result in collapsed components being removed completely, or simply being collapsed to an (invalid) Geometry of the same type. The default is to remove collapsed components.- Parameters:
removeCollapsed
- iftrue
collapsed components will be removed
-
setChangePrecisionModel
public void setChangePrecisionModel(boolean changePrecisionModel)
Deprecated.Sets whether thePrecisionModel
of the new reduced Geometry will be changed to be thePrecisionModel
supplied to specify the precision reduction.The default is to not change the precision model
- Parameters:
changePrecisionModel
- iftrue
the precision model of the created Geometry will be the the precisionModel supplied in the constructor.
