public final void append(PathIterator pi, boolean connect)
Appends the geometry of the specified PathIterator
object to the path, possibly connecting the new geometry to the existing path segments with a line segment. If the connect
parameter is true
and the path is not empty then any initial moveTo
in the geometry of the appended Shape
is turned into a lineTo
segment. If the destination coordinates of such a connecting lineTo
segment match the ending coordinates of a currently open subpath then the segment is omitted as superfluous. The winding rule of the specified Shape
is ignored and the appended geometry is governed by the winding rule specified for this path.

Transforms the geometry of this path using the specified AffineTransform
. The geometry is transformed in place, which permanently changes the boundary defined by this object.

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.
Note that the definition of insideness can lead to situations where points on the defining outline of the shape
may not be considered contained in the returned bounds
object, but only in cases where those points are also not considered contained in the original shape
.
If a point
is inside the shape
according to the contains(point)
method, then it must be inside the returned Rectangle2D
bounds object according to the contains(point)
method of the bounds
. Specifically:
shape.contains(p)
requires bounds.contains(p)
If a point
is not inside the shape
, then it might still be contained in the bounds
object:
bounds.contains(p)
does not imply shape.contains(p)

public final PathIterator getPathIterator(AffineTransform at)
Returns an iterator object that iterates along the Shape
boundary and provides access to the geometry of the Shape
outline. If an optional AffineTransform
is specified, the coordinates returned in the iteration are transformed accordingly.
Each call to this method returns a fresh PathIterator
object that traverses 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 implementing the Shape
interface isolate iterations that are in process from any changes that might occur to the original object's geometry during such iterations.
The iterator for this class is not multi-threaded safe, which means that the Path2D
class does not guarantee that modifications to the geometry of this Path2D
object do not affect any iterations of that geometry that are already in process.
