## Detailed Description

Represents a node in the queue of incoming messages.

This class contains necessary information about a message that is stored in the queue. Such a node can be used by the incoming thread from the reactor to dequeue and process the message by sending it to the higher layers of the ORB.

## Constructor & Destructor Documentation

TAO_Queued_Data::TAO_Queued_Data | ( | ACE_Allocator * | alloc = 0 | ) |

| Default Constructor.

TAO_Queued_Data::TAO_Queued_Data | ( | ACE_Message_Block * | mb,
|  | ACE_Allocator * | alloc = 0
| ) |

| Constructor.

TAO_Queued_Data::TAO_Queued_Data | ( | const TAO_Queued_Data & | qd | ) |

| Copy constructor.

## Member Function Documentation

TAO_Queued_Data * TAO_Queued_Data::duplicate | ( | TAO_Queued_Data & | qd | ) | `[static]`

| Duplicate ourselves. This creates a copy of ourselves on the heap and returns a pointer to the duplicated node.

TAO_Queued_Data * TAO_Queued_Data::get_queued_data | ( | ACE_Allocator * | alloc = 0 | ) | `[static]`

| Creation and deletion of a node in the queue.

void TAO_Queued_Data::release | ( | TAO_Queued_Data * | qd | ) | `[static]`

ACE_INLINE void TAO_Queued_Data::replace_data_block | ( | ACE_Message_Block & | mb | ) | `[static, private]`

| Replace the datablock with a one allocated on the heap or allocator

## Member Data Documentation

ACE_Allocator* TAO_Queued_Data::allocator_`[private]`

| The allocator used to allocate this class.

CORBA::Octet TAO_Queued_Data::byte_order_

| The byte order of the message that is stored in the node..

CORBA::Octet TAO_Queued_Data::major_version_

| Many protocols like GIOP have a major and minor version information that would be needed to read and decipher the message.

CORBA::Octet TAO_Queued_Data::minor_version_

CORBA::Long TAO_Queued_Data::missing_data_

| Data missing in the above message that hasn't been read or processed yet.

CORBA::Octet TAO_Queued_Data::more_fragments_

| Some messages can be fragmented by the protocol (this is an ORB level fragmentation on top of the TCP/IP fragmentation. This member indicates whether the message that we have recd. and queue already has more fragments that is missing..

ACE_Message_Block* TAO_Queued_Data::msg_block_

| The message block that contains the message.

TAO_Pluggable_Message_Type TAO_Queued_Data::msg_type_

| The message type of the message.

TAO_Queued_Data* TAO_Queued_Data::next_

| Pounter to the next element in the queue.
