Method Detail

isSerializable

public static boolean isSerializable(java.lang.Class c)

Returns true if a class implements Serializable and false otherwise.

Parameters:

c - the class.

Returns:

A boolean.

readPaint

public static java.awt.Paint readPaint(java.io.ObjectInputStream stream)
                                throws java.io.IOException,
                                       java.lang.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:

java.io.IOException - if there is an I/O problem.

java.lang.ClassNotFoundException - if there is a problem loading a class.

writePaint

public static void writePaint(java.awt.Paint paint,
                              java.io.ObjectOutputStream stream)
                       throws java.io.IOException

Serialises a Paint object.

Parameters:

paint - the paint object (null permitted).

stream - the output stream (null not permitted).

Throws:

java.io.IOException - if there is an I/O error.

readStroke

public static java.awt.Stroke readStroke(java.io.ObjectInputStream stream)
                                  throws java.io.IOException,
                                         java.lang.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:

java.io.IOException - if there is an I/O problem.

java.lang.ClassNotFoundException - if there is a problem loading a class.

writeStroke

public static void writeStroke(java.awt.Stroke stroke,
                               java.io.ObjectOutputStream stream)
                        throws java.io.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:

java.io.IOException - if there is an I/O error.

readShape

public static java.awt.Shape readShape(java.io.ObjectInputStream stream)
                                throws java.io.IOException,
                                       java.lang.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:

java.io.IOException - if there is an I/O problem.

java.lang.ClassNotFoundException - if there is a problem loading a class.

writeShape

public static void writeShape(java.awt.Shape shape,
                              java.io.ObjectOutputStream stream)
                       throws java.io.IOException

Serialises a Shape object.

Parameters:

shape - the shape object (null permitted).

stream - the output stream (null not permitted).

Throws:

java.io.IOException - if there is an I/O error.

readPoint2D

public static java.awt.geom.Point2D readPoint2D(java.io.ObjectInputStream stream)

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).
