Appends the specified coordinates to this Polygon.

  Appends the specified coordinates to this Polygon.

If an operation that calculates the bounding box of this Polygon has already been performed, such as getBounds or contains, then this method updates the bounding box.
Parameters:
- x - the specified X coordinate
- y - the specified Y coordinate
Since: 1.0
See Also: Polygon.getBounds(), Polygon.contains(java.awt.Point),

  Tests if the specified coordinates are inside the boundary of the Shape.

  Tests if the specified coordinates are inside the boundary of the
Shape.
Since: 1.2

  Tests if the interior of the Shape entirely contains the specified rectangular area.

  Tests if the interior of the Shape entirely contains the specified rectangular area. All coordinates that lie inside the rectangular area must lie within the Shape for the entire rectanglar area to be considered contained within the Shape.

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 rectangular area are prohibitively expensive.

This means that for some Shapes this method might return false even though the Shape contains the rectangular area. The Area class performs more accurate geometric computations than most Shape objects and therefore can be used if a more precise answer is required.
Since: 1.2

Parameters:

  Determines whether the specified Point is inside this Polygon.

  Determines whether the specified Point is inside this
Polygon.

  Tests if a specified Point2D is inside the boundary of the Shape.

  Tests if a specified Point2D is inside the boundary
of the Shape.
Since: 1.2

  Tests if the interior of the Shape entirely contains the specified Rectangle2D.

  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.
Since: 1.2

  Returns the bounds of this Polygon.

  Returns the bounds of this Polygon.
Returns: the bounds of this Polygon.
Since: 1.0

  Gets the bounding box of this Polygon.

  Gets the bounding box of this Polygon.
The bounding box is the smallest Rectangle whose
sides are parallel to the x and y axes of the
coordinate space, and can completely contain the Polygon.
Returns: a Rectangle that defines the bounds of this Polygon.
Since: 1.1

  Returns a high precision and more accurate bounding box of the Shape than the getBounds method.

  Returns a high precision and more accurate bounding box of
the Shape than the getBounds method.
Note that there is no guarantee that the returned
Rectangle2D is the smallest bounding box that encloses
the Shape, only that the Shape lies
entirely within the indicated Rectangle2D. The
bounding box returned by this method is usually tighter than that
returned by the getBounds method and never fails due
to overflow problems since the return value can be an instance of
the Rectangle2D that uses double precision values to
store the dimensions.
Since: 1.2

  Returns an iterator object that iterates along the boundary of this Polygon and provides access to the geometry of the outline of this Polygon.

  Returns an iterator object that iterates along the boundary of this
Polygon and provides access to the geometry
of the outline of this Polygon. An optional
AffineTransform can be specified so that the coordinates
returned in the iteration are transformed accordingly.
Returns: a {@link PathIterator} object that provides access to the geometry of this Polygon.
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
Since: 1.2

  Returns an iterator object that iterates along the boundary of the Shape and provides access to the geometry of the outline of the Shape.

  Returns an iterator object that iterates along the boundary of
the Shape and provides access to the geometry of the
outline of the Shape. Only SEG_MOVETO, SEG_LINETO, and
SEG_CLOSE point types are returned by the iterator.
Since polygons are already flat, the flatness parameter
is ignored. An optional AffineTransform can be specified
in which case the coordinates returned in the iteration are transformed
accordingly.
Returns: a PathIterator object that provides access to the Shape object's geometry.
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 amount that the control points for a given curve can vary from colinear before a subdivided curve is replaced by a straight line connecting the endpoints. Since polygons are already flat the flatness parameter is ignored.
Since: 1.2

  Determines whether the specified coordinates are contained in this Polygon.

  Determines whether the specified coordinates are contained in this
Polygon.
Returns: {@code true} if this {@code Polygon} contains the specified coordinates {@code (x,y)}; {@code false} otherwise.
Parameters:
- x - the specified X coordinate to be tested
- y - the specified Y coordinate to be tested

  Tests if the interior of the Shape intersects the interior of a specified rectangular area.

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

The Shape.intersects() method allows a Shape implementation to conservatively return true when:

• there is a high probability that the rectangular area 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 rectangular area 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.
Since: 1.2

  Tests if the interior of the Shape intersects the interior of a specified Rectangle2D.

  Invalidates or flushes any internally-cached data that depends on the vertex coordinates of this Polygon.

  Invalidates or flushes any internally-cached data that depends
on the vertex coordinates of this Polygon.
This method should be called after any direct manipulation
of the coordinates in the xpoints or
ypoints arrays to avoid inconsistent results
from methods such as getBounds or contains
that might cache data from earlier computations relating to
the vertex coordinates.
Since: 1.4

  Resets this Polygon object to an empty polygon.

  Resets this Polygon object to an empty polygon.
The coordinate arrays and the data in them are left untouched
but the number of points is reset to zero to mark the old
vertex data as invalid and to start accumulating new vertex
data at the beginning.
All internally-cached data relating to the old vertices
are discarded.
Note that since the coordinate arrays from before the reset
are reused, creating a new empty Polygon might
be more memory efficient than resetting the current one if
the number of vertices in the new polygon data is significantly
smaller than the number of vertices in the data from before the
reset.
