append

public final void append(PathIterator pi,
                         boolean connect)

Class is disabled.

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.

Specified by:

append in class Path2D

Parameters:

pi - the PathIterator whose geometry is appended to this path

connect - a boolean to control whether or not to turn an initial moveTo segment into a lineTo segment to connect the new geometry to the existing path

Since:

1.6

transform

public final void transform(AffineTransform at)

Class is disabled.

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.

Specified by:

transform in class Path2D

Parameters:

at - the AffineTransform used to transform the area

Since:

1.6

getBounds2D

public final Rectangle2D getBounds2D()

Class is disabled.

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.

Specified by:

getBounds2D in interface Shape

Returns:

an instance of Rectangle2D that is a high-precision bounding box of the Shape.

Since:

1.6

See Also:

Shape.getBounds()

getPathIterator

public PathIterator getPathIterator(AffineTransform at)

Class is disabled.

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.

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

Returns:

a new PathIterator object, which independently traverses the geometry of the Shape.

Since:

1.6

clone

public final Object clone()

Class is disabled.

Creates a new object of the same class as this object.

Specified by:

clone in class Path2D

Returns:

a clone of this instance.

Throws:

OutOfMemoryError - if there is not enough memory.

Since:

1.6
