public abstract class RectangularShape
- extends Object
- implements Shape, Cloneable
RectangularShape is the base class for a number of
Shape
objects whose geometry is defined by a rectangular frame. This class does not directly specify any specific geometry by itself, but merely provides manipulation methods inherited by a whole category of Shape objects. The manipulation methods provided by this class can be used to query and modify the rectangular frame, which provides a reference for the subclasses to define their geometry.

contains
public boolean contains(Point2D p)
-

Point2D
Point2D
is inside the boundary of the Shape.
-
-
Specified by:
-
contains
in interface
Shape
-
-
Parameters:
-
p - the specified Point2D

Point2D is inside the
boundary of the Shape;
Shape object's boundary;
false otherwise. -
Since:
-

intersects
public boolean intersects(Rectangle2D r)
-
Tests if the interior of the Shape intersects the interior of a specified Rectangle2D. The Shape.intersects() method allows a Shape implementation to conservatively return true when:
-
there is a high probability that the Rectangle2D and the Shape intersect, but
-
the calculations to accurately determine this intersection are prohibitively expensive.
This means that for some Shapes this method might return true even though the Rectangle2D does not intersect the Shape. The
Area
class performs more accurate computations of geometric intersection than most Shape objects and therefore can be used if a more precise answer is required.
Tests if the interior of theShape intersects the interior of a specified Rectangle2D.

Specified by:

intersects
in interface
Shape
-
-
Parameters:
-
r - the specified Rectangle2D
-
Returns:
-
true if the interior of the Shape and the interior of the specified Rectangle2D intersect, or are both highly likely to intersect and intersection calculations would be too expensive to perform; false otherwise.
true if the Shape and the specified Rectangle2D intersect each other; false otherwise.

Shape.intersects(double, double, double, double)
contains
public boolean contains(Rectangle2D r)
-
Tests if the interior of the Shape entirely contains the specified Rectangle2D. The Shape.contains() method allows a Shape implementation to conservatively return false when:
-
the intersect method returns true and
-
the calculations to determine whether or not the Shape entirely contains the Rectangle2D are prohibitively expensive.
This means that for some Shapes this method might return false even though the Shape contains the Rectangle2D. The
Area
class performs more accurate geometric computations than most Shape objects and therefore can be used if a more precise answer is required.

getBounds
public Rectangle getBounds()
-
Returns an integer
Rectangle
that completely encloses the Shape. Note that there is no guarantee that the returned 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 Shape if the Shape overflows the limited range of the integer data type. The getBounds2D method generally returns a tighter bounding box due to its greater flexibility in representation.
Returns the bounding box of the Shape.

getPathIterator
public PathIterator getPathIterator(AffineTransform at,
double flatness)
-
Returns an iterator object that iterates along the Shape object's boundary and provides access to a flattened view of the outline of the Shape object's geometry.
Only SEG_MOVETO, SEG_LINETO, and SEG_CLOSE point types will be returned by the iterator.
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. An optional
AffineTransform
can be specified so that the coordinates returned in the iteration are transformed accordingly.
-
-
Specified by:
-
getPathIterator
in interface
Shape
-
-
Parameters:
-
at - an optional AffineTransform to be applied to the coordinates as they are returned in the iteration, or null if untransformed coordinates are desired.
-
flatness - the maximum distance that the line segments used to approximate the curved segments are allowed to deviate from any point on the original curve
-
Returns:
-
a PathIterator object that provides access to the Shape object's flattened geometry.
