Geometry |
reduce(Geometry geom) |
|
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.

will be changed to be the PrecisionModel
supplied to
specify the precision reduction.
The default is to not change the precision model

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