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.

The ACE_Message_Block contained within this class may contain a chain of message blocks (usually when GIOP fragments are involved). In that case consolidate () needs to be called prior to being sent to higher layers of the ORB when the GIOP fragment chain is complete.

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

CORBA::Octet TAO_Queued_Data::byte_order ( void ) const

Get byte_order.

int TAO_Queued_Data::consolidate ( void )

Consolidate this fragments chained message blocks into one.

Returns:: -1 if consolidation failed, eg out or memory, otherwise 0

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_GIOP_Message_Version const & TAO_Queued_Data::giop_version ( void ) const

Get the GIOP version.

TAO_Queued_Data * TAO_Queued_Data::make_queued_data	(	ACE_Allocator *	message_buffer_alloc = `0`,
		ACE_Allocator *	input_cdr_alloc = `0`,
		ACE_Data_Block *	db = `0`
	)		`[static]`

Creation of a node in the queue.

size_t TAO_Queued_Data::missing_data ( void ) const

Get missing data.

void TAO_Queued_Data::missing_data ( size_t data )

Set missing data.

CORBA::Boolean TAO_Queued_Data::more_fragments ( void ) const

Get more fragments.

ACE_Message_Block * TAO_Queued_Data::msg_block ( void ) const

Get message block.

void TAO_Queued_Data::msg_block ( ACE_Message_Block * mb )

Set message block.

GIOP::MsgType TAO_Queued_Data::msg_type ( void ) const

Get message type.

TAO_Queued_Data * TAO_Queued_Data::next ( void ) const

Get next.

void TAO_Queued_Data::next ( TAO_Queued_Data * qd )

Set next.

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

Deletion of a node from the queue.

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

void TAO_Queued_Data::state ( const TAO_GIOP_Message_State & state )

Set the state.

const TAO_GIOP_Message_State & TAO_Queued_Data::state ( void ) const

Get the state.

Member Data Documentation

ACE_Allocator* TAO_Queued_Data::allocator_ [private]

The allocator used to allocate this class.

size_t TAO_Queued_Data::missing_data_ [private]

Data missing in the above message that hasn't been read or processed yet, the value TAO_MISSING_DATA_UNDEFINED indicates it hasn't been processed yet, otherwise greater or equal zero.

ACE_Message_Block* TAO_Queued_Data::msg_block_ [private]

The message block that contains the message.

TAO_Queued_Data* TAO_Queued_Data::next_ [private]

Pounter to the next element in the queue.

TAO_GIOP_Message_State TAO_Queued_Data::state_ [private]

State of this queued data.
