public PathIterator getPathIterator(AffineTransform at)
Ellipse2D
.
The iterator for this class is multi-threaded safe, which means
that this Ellipse2D
class guarantees that
modifications to the geometry of this Ellipse2D
object do not affect any iterations of that geometry that
are already in process.
at
- an optional AffineTransform
to be applied to
the coordinates as they are returned in the iteration, or
null
if untransformed coordinates are desired
PathIterator
object that returns the
geometry of the outline of this Ellipse2D
,
one segment at a time.
