#566 Serialization support

[Moritz Hoffmann]

Add serialization support to ooRexx. This includes the implementation, documentation and testing of a basic serialization framework and the required changes to the ooRexx core classes. It is required to:

• Add a Serializable class providing read/writeObject methods without implementation.
• Let core classes inherit from Serializable when applicable and implement read/writeObject methods
• Add basic serialization support framework to handle the serialization/deserialization.

The implementation is already part of the trunk.

[Moritz Hoffmann]

Removed serialization support from 4.2.0 branch in [r9670].

Moritz, as far as I can see the SVN trunk (i.e. 5.0.0) contains a few pieces of Serializable, e. g. interpreter\RexxClasses\Serializable.orx and the readObject / writeObject methods of CircularQueue.

Will you want to add full support for Serializable for 5.0.0 or should above be removed and the RFE be postponed?

References to Serializable class removed from 5.0 trunk with revision [r10991].
