<DD>Tests if the interior of the <code>Shape</code> intersects the 
 interior of a specified rectangular area.
 The rectangular area is considered to intersect the <code>Shape</code> 
 if any point is contained in both the interior of the 
 <code>Shape</code> and the specified rectangular area.

 This method might conservatively return <code>true</code> when:

 are prohibitively expensive.

<DD>Tests if the interior of the <code>Shape</code> entirely contains 
 the specified rectangular area.  All coordinates that lie inside
 the rectangular area must lie within the <code>Shape</code> for the

<DL>
<DD>Returns an iterator object that iterates along the 
 <code>Shape</code> boundary and provides access to the geometry of the 
 <code>Shape</code> outline.  If an optional <A HREF="../../java/awt/geom/AffineTransform.html"><CODE>AffineTransform</CODE></A>
 is specified, the coordinates returned in the iteration are
 transformed accordingly.
 <p>
 Each call to this method returns a fresh <code>PathIterator</code>
 object that traverses the geometry of the <code>Shape</code> object
 independently from any other <code>PathIterator</code> objects in use
 at the same time.
 <p>
 It is recommended, but not guaranteed, that objects 
 implementing the <code>Shape</code> interface isolate iterations
 that are in process from any changes that might occur to the original
 object's geometry during such iterations.
 <p>
 Before using a particular implementation of the <code>Shape</code> 
 interface in more than one thread simultaneously, refer to its 
 documentation to verify that it guarantees that iterations are isolated 
 from modifications.<DD><DL>

<DL>
<DD>Returns an iterator object that iterates along the <code>Shape</code>
 boundary and provides access to a flattened view of the
 <code>Shape</code> outline geometry.
 <p>
 Only SEG_MOVETO, SEG_LINETO, and SEG_CLOSE point types are
 returned by the iterator.
 <p>
 If an optional <code>AffineTransform</code> is specified,
 the coordinates returned in the iteration are transformed
 accordingly.
 <p>
 The amount of subdivision of the curved segments is controlled
 by the <code>flatness</code> 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.
