public int getDimension()
Geometry
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 0-dimensional geometry (e.g. a Point)
may have a coordinate dimension of 3 (X,Y,Z).

Geometry

s are exactly equal,
up to a specified distance tolerance.
Two Geometries are exactly equal within a distance tolerance
if and only if:
GeometryFactory
, the SRID
,
or the userData
fields.
To properly test equality between different geometries,
it is usually necessary to Geometry.normalize()
them first.
