## 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.

## Member Function Documentation

virtual void TAO_Unbounded_Sequence< CORBA::Octet >::_allocate_buffer | ( | CORBA::ULong | length | ) | `[virtual]`

| Implement the methods for all the sequence, please see TAO_Base_Sequence. Implements TAO_Base_Sequence.

virtual void TAO_Unbounded_Sequence< CORBA::Octet >::_deallocate_buffer | ( | void |  | ) | `[virtual]`

| Must deallocate the buffer and then set it to zero. Implements TAO_Base_Sequence.

void TAO_Unbounded_Sequence< CORBA::Octet >::_tao_any_destructor | ( | void * |  | ) | `[static]`

| Use in the implementation of insertion and extraction operators from CORBA::Any Reimplemented in CORBA::OctetSeq.

CORBA::Octet* TAO_Unbounded_Sequence< CORBA::Octet >::allocbuf | ( | CORBA::ULong |  | ) | `[static]`

| Allocate storage for the sequence, please note that the storage is always held in a ACE_Message_Block.

void TAO_Unbounded_Sequence< CORBA::Octet >::freebuf | ( | CORBA::Octet * |  | ) | `[static]`

| Free the storage.

const CORBA::Octet* TAO_Unbounded_Sequence< CORBA::Octet >::get_buffer | ( | void |  | ) | const

CORBA::Octet* TAO_Unbounded_Sequence< CORBA::Octet >::get_buffer | ( | CORBA::Boolean | orphan = 0 | ) |

ACE_Message_Block* TAO_Unbounded_Sequence< CORBA::Octet >::mb | ( | void |  | ) | const

| Returns the underlying message block, the caller must *not* release the copy.

TAO_Unbounded_Sequence<CORBA::Octet>& TAO_Unbounded_Sequence< CORBA::Octet >::operator= | ( | const TAO_Unbounded_Sequence< CORBA::Octet > & |  | ) |

ACE_INLINE const CORBA::Octet & TAO_Unbounded_Sequence< CORBA::Octet >::operator[] | ( | CORBA::ULong |  | ) | const

CORBA::Octet& TAO_Unbounded_Sequence< CORBA::Octet >::operator[] | ( | CORBA::ULong |  | ) |

| See the general description in "Sequence_T.h" NOTE: This last two methods can be rendered useless in certain cases, see below.

void TAO_Unbounded_Sequence< CORBA::Octet >::replace | ( | CORBA::ULong | length,
|  | const ACE_Message_Block * | mb
| ) |

| Replaces the current buffer with <mb>, using only <length> bytes. It takes a duplicate of <mb> so the user still owns it.

void TAO_Unbounded_Sequence< CORBA::Octet >::replace | ( | CORBA::ULong | max,
|  | CORBA::ULong | length,
|  | CORBA::Octet * | data,
|  | CORBA::Boolean | release = 0
| ) |

| See the general description of this methods in "Sequence_T.h".

TAO_Unbounded_Sequence< CORBA::Octet >::TAO_Unbounded_Sequence | ( | CORBA::ULong | length,
|  | const ACE_Message_Block * | mb
| ) |

| Create a sequence of octets from a single message block (i.e. it ignores any chaining in the meesage block).

TAO_Unbounded_Sequence< CORBA::Octet >::TAO_Unbounded_Sequence | ( | const TAO_Unbounded_Sequence< CORBA::Octet > & |  | ) |

| 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.
