Method Detail

isSerializable

public static boolean isSerializable(Class c)

Returns true if a class implements Serializable and false otherwise.

Parameters:

c - the class.

Returns:

A boolean.

readPaint

public static Paint readPaint(ObjectInputStream stream)
                       throws IOException,
                              ClassNotFoundException

Reads a Paint object that has been serialised by the writePaint(Paint, ObjectOutputStream) method.

Parameters:

stream - the input stream (null not permitted).

Returns:

The paint object (possibly null).

Throws:

IOException - if there is an I/O problem.

ClassNotFoundException - if there is a problem loading a class.

writePaint

public static void writePaint(Paint paint,
              ObjectOutputStream stream)
                       throws IOException

Serialises a Paint object.

Parameters:

paint - the paint object (null permitted).

stream - the output stream (null not permitted).

Throws:

IOException - if there is an I/O error.

readStroke

public static Stroke readStroke(ObjectInputStream stream)
                         throws IOException,
                                ClassNotFoundException

Reads a Stroke object that has been serialised by the writeStroke(Stroke, ObjectOutputStream) method.

Parameters:

stream - the input stream (null not permitted).

Returns:

The stroke object (possibly null).

Throws:

IOException - if there is an I/O problem.

ClassNotFoundException - if there is a problem loading a class.

writeStroke

public static void writeStroke(Stroke stroke,
               ObjectOutputStream stream)
                        throws IOException

Serialises a Stroke object. This code handles the BasicStroke class which is the only Stroke implementation provided by the JDK (and isn't directly Serializable).

Parameters:

stroke - the stroke object (null permitted).

stream - the output stream (null not permitted).

Throws:

IOException - if there is an I/O error.

readShape

public static Shape readShape(ObjectInputStream stream)
                       throws IOException,
                              ClassNotFoundException

Reads a Shape object that has been serialised by the writeShape(Shape, ObjectOutputStream) method.

Parameters:

stream - the input stream (null not permitted).

Returns:

The shape object (possibly null).

Throws:

IOException - if there is an I/O problem.

ClassNotFoundException - if there is a problem loading a class.

writeShape

public static void writeShape(Shape shape,
              ObjectOutputStream stream)
                       throws IOException

Serialises a Shape object.

Parameters:

shape - the shape object (null permitted).

stream - the output stream (null not permitted).

Throws:

IOException - if there is an I/O error.

readPoint2D

public static Point2D readPoint2D(ObjectInputStream stream)
                           throws IOException

Reads a Point2D object that has been serialised by the writePoint2D(Point2D, ObjectOutputStream) method.

Parameters:

stream - the input stream (null not permitted).

Returns:

The point object (possibly null).

Throws:

IOException - if there is an I/O problem.

writePoint2D

public static void writePoint2D(Point2D p,
                ObjectOutputStream stream)
                         throws IOException

Serialises a Point2D object.

Parameters:

p - the point object (null permitted).

stream - the output stream (null not permitted).

Throws:

IOException - if there is an I/O error.

readAttributedString

public static AttributedString readAttributedString(ObjectInputStream stream)
                                             throws IOException,
                                                    ClassNotFoundException

writeAttributedString

public static void writeAttributedString(AttributedString as,
                         ObjectOutputStream stream)
                                  throws IOException
