Detailed Description

An unbounded sequence of Octets.

Marshalling and demarshalling octet sequences can be highly optimize, for instance at demarshalling we don't require a copy from the CDR buffer to the octet sequence buffer, we can simply hold a duplicate of the underlying ACE_Message_Block. Specializing the TAO_Unbounded_Sequence<T> parametric class, is an excellent way to achieve this optimizations.

The copy constructor and assignment operators *do* copy the data, though we could simply duplicate the ref count in the ACE_Message_Block this will change the semantics for this operations.
