                               boolean compressed)
                        throws IOException

This routine would stream out the give object, uncompressed or compressed depending on the given flag, and store the streamed contents in the return byte array. The output contents could only be read by the corresponding "streamIn" method of this class.

Parameters:

object -

compressed -

Returns:

Throws:

IOException

streamOut

public static void streamOut(OutputStream out,
                             Object object)
                      throws IOException

This method would stream out the given object to the given output stream uncompressed. The output contents could only be read by the corresponding "streamIn" method of this class.

Parameters:

out -

object -

Throws:

IOException

streamOut

public static void streamOut(OutputStream out,
                             Object object,
                             boolean compressed)
                      throws IOException

This method would stream out the given object to the given output stream uncompressed or compressed depending on the given flag. The output contents could only be read by the corresponding "streamIn" methods of this class.

Parameters:

out -

object -

Throws:

IOException

streamIn

public static Object streamIn(byte[] bytes)
                       throws IOException,
                              ClassNotFoundException

This method reads the contents from the given byte array and returns the object. It is expected that the contents in the given buffer was not compressed, and the content stream was written by the corresponding streamOut methods of this class.

Parameters:

bytes -

Returns:

Throws:

IOException

ClassNotFoundException

streamIn

public static Object streamIn(byte[] bytes,
                              ClassLoader classLoader)
