com.vividsolutions.jts.precision.SimpleGeometryPrecisionReducer
public class SimpleGeometryPrecisionReducer
extends java.lang.Object
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.
SimpleGeometryPrecisionReducer
public SimpleGeometryPrecisionReducer(PrecisionModel pm)
setChangePrecisionModel
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 reduction. The default is to not change the precision model
changePrecisionModel
- if true
the precision model of the created Geometry will be the
the precisionModel supplied in the constructor.
setRemoveCollapsedComponents
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.
removeCollapsed
- if true
collapsed components will be removed
