In general, the array cannot be assumed to be the actual internal
storage for the vertices. Thus modifying the array
may not modify the geometry itself.
Use the CoordinateSequence.setOrdinate(int, int, double)
method
(possibly on the components) to modify the underlying data.
If the coordinates are modified,
Geometry.geometryChanged()
must be called afterwards.

Note this test is for topological emptiness,
not structural emptiness.
A collection containing only empty elements is reported as empty.
To check structural emptiness use Geometry.getNumGeometries()
.
public boolean isSimple()
Geometry
Geometry
is simple.
The SFS definition of simplicity
follows the general rule that a Geometry is simple if it has no points of
selftangency, selfintersection or other anomalous points.
Simplicity is defined for each Geometry
subclass as follows:
isSimple
tests for this condition and reports false
if it is not met.
(This is a looser test than checking for validity).
Geometry
s are always simple.

public int getDimension()

Note that this is a different concept to the dimension of
the vertex Coordinate
s.
The geometry dimension can never be greater than the coordinate dimension.
For example, a 0dimensional geometry (e.g. a Point)
may have a coordinate dimension of 3 (X,Y,Z).

to normal form (or
canonical form ). Normal form is a unique representation for Geometry
s. It can be used to test whether two Geometry
s are equal
in a way that is independent of the ordering of the coordinates within
them. Normal form equality is a stronger condition than topological
equality, but weaker than pointwise equality. The definitions for normal
form use the standard lexicographical ordering for coordinates. "Sorted in
order of coordinates" means the obvious extension of this ordering to
sequences of coordinates.
NOTE that this method mutates the value of this geometry inplace. If this is not safe and/or wanted, the geometry should be cloned prior to normalization.
