Method Summary

Modifier and Type	Method and Description
OSerializableStream	fromStream(byte[] iStream) Unmarshalls the object.
byte[]	toStream() Marshalls the object.

Method Detail

toStream

byte[] toStream()
         throws OSerializationException

Marshalls the object. Transforms the current object in byte[] form to being stored or transferred over the network.

Returns:

The byte array representation of the object

Throws:

OSerializationException - if the marshalling does not succeed

See Also:

fromStream(byte[])

fromStream

OSerializableStream fromStream(byte[] iStream)
                        throws OSerializationException

Unmarshalls the object. Fills the current object with the values contained in the byte array representation restoring a previous state. Usually byte[] comes from the storage or network.

Parameters:

iStream - byte array representation of the object

Returns:

The Object instance itself giving a "fluent interface". Useful to call multiple methods in chain.

Throws:

OSerializationException - if the unmarshalling does not succeed
