Method Detail

serialize

public static final byte[] serialize(Object obj)

Serialize an object using the Java serialization mechanisms.

Parameters:

obj - A Serializable object.

Returns:

The serialized object state.

deserialize

public static final Object deserialize(byte[] b)

De-serialize an object using the Java serialization mechanisms.

Parameters:

b - A byte[] containing a serialized object.

Returns:

The de-serialized object -or- null iff the byte[] reference is null.

deserialize

public static final Object deserialize(byte[] b,
                 int off,
                 int len)

De-serialize an object using the Java serialization mechanisms.

Parameters:

b - A byte[] containing a serialized object.

off - The offset of the first byte to de-serialize.

len - The #of bytes in the object record.

Returns:

The de-serialized object.

deserialize

public static final Object deserialize(InputStream is)

De-serialize an object using the Java serialization mechanisms.

Parameters:

is - The input stream from which to read the serialized data.

Returns:

The de-serialized object.

deserialize

public static final Object deserialize(ByteBuffer buf)

De-serialize an object using the Java serialization mechanisms.

Parameters:

buf - A buffer containing a serialized object. The bytes from Buffer.position() to Buffer.limit() will be de-serialized and the position will be advanced to the limit.

Returns:

The de-serialized object.
