to the path, possibly connecting the new geometry to the existing
path segments with a line segment.
If the connect
parameter is true
and the
path is not empty then any initial moveTo
in the
geometry of the appended Shape
is turned into a
lineTo
segment.
If the destination coordinates of such a connecting lineTo
segment match the ending coordinates of a currently open
subpath then the segment is omitted as superfluous.
The winding rule of the specified Shape
is ignored
and the appended geometry is governed by the winding
rule specified for this path.public final void transform(AffineTransform at)

than the getBounds
method.
Note that there is no guarantee that the returned
Rectangle2D
is the smallest bounding box that encloses
the Shape
, only that the Shape
lies
entirely within the indicated Rectangle2D
. The
bounding box returned by this method is usually tighter than that
returned by the getBounds
method and never fails due
to overflow problems since the return value can be an instance of
the Rectangle2D
that uses double precision values to
store the dimensions.
Note that the
definition of insideness can lead to situations where points
on the defining outline of the shape
may not be considered
contained in the returned bounds
object, but only in cases
where those points are also not considered contained in the original
shape
.
If a point
is inside the shape
according to the
contains(point)
method, then it must
be inside the returned Rectangle2D
bounds object according
to the contains(point)
method of the
bounds
. Specifically:
shape.contains(p)
requires bounds.contains(p)
If a point
is not inside the shape
, then it might
still be contained in the bounds
object:
bounds.contains(p)
does not imply shape.contains(p)

Shape
outline. If an optional AffineTransform
is specified, the coordinates returned in the iteration are
transformed accordingly.
Each call to this method returns a fresh PathIterator
object that traverses the geometry of the Shape
object
independently from any other PathIterator
objects in use
at the same time.
It is recommended, but not guaranteed, that objects
implementing the Shape
interface isolate iterations
that are in process from any changes that might occur to the original
object's geometry during such iterations.
The iterator for this class is not multithreaded safe,
which means that the Path2D
class does not
guarantee that modifications to the geometry of this
Path2D
object do not affect any iterations of
that geometry that are already in process.
