public final class LiteShape2
extends java.lang.Object
implements java.awt.Shape, java.lang.Cloneable
This implementation supports the use of MathTransform and can be constructed with a Decimation stratagy object (allowing you to fine tune the process by which a Geometry is simplified into a Shape).
This implementation is very careful about cloning; and has the ability to go faster when you are using a LiteCoordinateSequenceFactory behind your geometry classes.

Rectangle
is the smallest bounding box that encloses the
Shape
, only that the Shape
lies entirely
within the indicated Rectangle
. The returned
Rectangle
might also fail to completely enclose the

overflows the limited
range of the integer data type. The getBounds2D

generally returns a tighter bounding box due to its greater flexibility

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.
Before using a particular implementation of the Shape
interface in more than one thread simultaneously, refer to its
documentation to verify that it guarantees that iterations are isolated
from modifications.

Only SEG_MOVETO, SEG_LINETO, and SEG_CLOSE point types are returned by the iterator.
If an optional AffineTransform
is specified, the
coordinates returned in the iteration are transformed accordingly.
The amount of subdivision of the curved segments is controlled by the
flatness
parameter, which specifies the maximum distance
that any point on the unflattened transformed curve can deviate from the
returned flattened path segments. Note that a limit on the accuracy of
the flattened path might be silently imposed, causing very small
flattening parameters to be treated as larger values. This limit, if
there is one, is defined by the particular implementation that is used.
