ClassDescriptionThe
AffineTransform
class represents a 2D affine transform that performs a linear mapping from 2D coordinates to other 2D coordinates that preserves the "straightness" and "parallelness" of lines.TheDimension2D
class is to encapsulate a width and a height dimension.ThePathIterator
interface provides the mechanism for objects that implement theShape
interface to return the geometry of their boundary by allowing a caller to retrieve the path of that boundary a segment at a time.ThePoint2D
class defines a point representing a location in(x,y)
coordinate space.TheRectangle2D
class describes a rectangle defined by a location(x,y)
and dimension(w x h)
.RectangularShape
is the base class for a number ofShape
objects whose geometry is defined by a rectangular frame.

class represents a 2D affine transform that performs a linear mapping from 2D coordinates to other 2D coordinates that preserves the "straightness" and "parallelness" of lines.Arc2D
is the abstract superclass for all objects that store a 2D arc defined by a framing rectangle, start angle, angular extent (length of the arc), and a closure type (OPEN
,CHORD
, orPIE
).AnArea
object stores and manipulates a resolutionindependent description of an enclosed area of 2dimensional space.TheCubicCurve2D
class defines a cubic parametric curve segment in(x,y)
coordinate space.TheDimension2D
class is to encapsulate a width and a height dimension.TheEllipse2D
class describes an ellipse that is defined by a framing rectangle.ThisLine2D
represents a line segment in(x,y)
coordinate space.TheNoninvertibleTransformException
class represents an exception that is thrown if an operation is performed requiring the inverse of anAffineTransform
object but theAffineTransform
is in a noninvertible state.ThePath2D
class provides a simple, yet flexible shape which represents an arbitrary geometric path.TheFloat
class defines a geometric path with coordinates stored in single precision floating point.ThePathIterator
interface provides the mechanism for objects that implement theShape
interface to return the geometry of their boundary by allowing a caller to retrieve the path of that boundary a segment at a time.ThePoint2D
class defines a point representing a location in(x,y)
coordinate space.TheQuadCurve2D
class defines a quadratic parametric curve segment in(x,y)
coordinate space.TheRectangle2D
class describes a rectangle defined by a location(x,y)
and dimension(w x h)
.RectangularShape
is the base class for a number ofShape
objects whose geometry is defined by a rectangular frame.TheRoundRectangle2D
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.
