public boolean isSimple()
Geometry
Geometry
not simple.
Subclasses provide their own definition of "simple". If
this Geometry
is empty, returns true
. In general, the SFS specifications of simplicity seem to follow the following rule:
Geometry
s, isSimple
= true
.
isSimple

public Geometry getBoundary()
Geometry
Geometry
is empty. For a discussion of this function, see the OpenGIS Simple
Features Specification. As stated in SFS Section 2.1.13.1, "the boundary
of a Geometry is a set of Geometries of the next lower dimension."
getBoundary
in class GeometryCollection
public boolean equalsExact(Geometry other, double tolerance)
Geometry
Geometry
s are exactly equal,
up to a specified tolerance.
Two Geometries are exactly within a tolerance equal iff:
Geometry
s are
composites and any children are not Geometry
s, returns
false.
