Method Summary  
boolean  contains(double x,
double y,
double w,
double h)
Tests if the interior of the Shape entirely contains the given rectangular area. 
boolean  contains(double x,
double y)
Tests if a given coordinate is inside the boundary of the shape. 
boolean  contains(Point2D p)
Tests if a given Point is inside the boundary of the shape. 
boolean  contains(Rectangle2D r)
Test if the interior of the Shape entirely contains the given Rectangle. 
Rectangle  getBounds()
Returns an integer Rectangle which completely encloses the Shape. 
Rectangle2D  getBounds2D()
Returns a high precision and more accurate bounding box of the Shape than the getBounds method. 
PathIterator  getPathIterator(AffineTransform at,
double flatness)
Return an iterator object that iterates along the boundary of the shape and provides access to a flattened view of the geometry of the outline of the shape. 
PathIterator  getPathIterator(AffineTransform at)
Return an iterator object that iterates along the boundary of the shape and provides access to the geometry of the outline of the shape. 
boolean  intersects(double x,
double y,
double w,
double h)
Tests if the interior of the Shape intersects the interior of a given rectangular area. 
boolean  intersects(Rectangle2D r)
Tests if the interior of the Shape intersects the interior of a given Rectangle.

public boolean intersects(double x, double y, double w, double h)
This method may conservatively return true when the Shape and the rectangle do not actually overlap if there is a high probability that there is an intersection and the calculations to more accurately detect the intersection would be prohibitively expensive. The Area class can be used to perform more accurate computations of geometric intersection for any Shape object if a more precise answer is required.

public boolean contains(double x, double y, double w, double h)
This method may conservatively return false when the rectangle is actually contained entirely within the Shape as long as the intersects method returns true in that case and the calculations to more accurately detect the containment would be prohibitively expensive. The Area class can be used to perform more accurate computations of geometric intersection for any Shape object if a more precise answer is required.

public PathIterator getPathIterator(AffineTransform at)
Each call to this method will return a fresh PathIterator object that will traverse the geometry of the Shape object independently from any other PathIterator objects in use at the same time. It is recommended, but not guaranteed, that objects which implement the Shape interface attempt to isolate the iterations that are in process from any changes that occur to the original object's geometry should the geometry be modified while such an iteration is taking place. Consult the documentation for a given geometry object that implements this interface to see if it provides any guarantees about the isolation of iterations from modifications before using such an object in more than one thread at the same time.

 an optional AffineTransform to be applied to the
coordinates as they are returned in the iteration, or null
if the untransformed coordinates are desired.public PathIterator getPathIterator(AffineTransform at, double flatness)
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 is allowed to deviate from the flattened path segments
that are returned.
Note that there may be a silently imposed limit on the accuracy
of the flattened path which will cause very small flattening
parameters to be be treated as a larger value defined by the
implementation.
Only SEG_MOVETO, SEG_LINETO, and SEG_CLOSE point types will
be returned by the iterator.

for a given curve can vary from colinear before a subdivided
curve is replaced by a straight line connecting the endpoints.
