java.awt.geom.RoundRectangle2D
The RoundRectangle2D class defines a rectangle with
rounded corners defined by a location (x, y), a
dimension (w x h), and the width and height of an arc
with which to round the corners.
This class is the abstract superclass for all objects that store a 2D rounded rectangle. The actual storage representation of the coordinates is left to the subclass.
| Nested Class Summary | |
static class |
RoundRectangle2D.Double
The Double class defines a rectangle with rounded
corners all specified in double coordinates. |
static class |
RoundRectangle2D.Float
The Float class defines a rectangle with rounded
corners all specified in float coordinates. |
| Constructor Summary | |

RoundRectangle2D.
The iterator for this class is multi-threaded safe, which means
that this RoundRectangle2D class guarantees that
modifications to the geometry of this RoundRectangle2D
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
RoundRectangle2D, one segment at a time.
