Class SimpleGeometryPrecisionReducer

Hierarchy: Object , SimpleGeometryPrecisionReducer

public class SimpleGeometryPrecisionReducer

Reduces the precision of the coordinates of a Geometry according to the supplied PrecisionModel, 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.

public SimpleGeometryPrecisionReducer(PrecisionModel pm)

public 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.

Parameters:: g - g; precModel - precModel

Returns:: the reduced geometry

public 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. The default is to remove collapsed components.

Parameters:: removeCollapsed - removeCollapsed if true collapsed components will be removed

public 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.

The default is to not change the precision model

Parameters:: changePrecisionModel - changePrecisionModel if true the precision model of the created Geometry will be the the precisionModel supplied in the constructor.
