Detailed Description

Specialize TAO_Queued_Message for asynch requests, i.e. oneways sent with SYNC_NONE policy.

Constructor & Destructor Documentation

◆ TAO_Asynch_Queued_Message() [1/3]

TAO_Asynch_Queued_Message::TAO_Asynch_Queued_Message	(	const ACE_Message_Block *	contents,
		TAO_ORB_Core *	oc,
		ACE_Time_Value *	timeout,
		ACE_Allocator *	alloc,
		bool	is_heap_allocated
	)

Constructor.

Parameters

contents	The message block chain that must be sent.
alloc	Allocator used for creating `this` object.
timeout	The relative timeout after which this message should be expired.

Todo:: I'm almost sure this class will require a callback interface for AMIs sent with SYNC_NONE policy. Those guys need to hear when the connection timeouts or closes, but cannot block waiting for the message to be delivered.

◆ ~TAO_Asynch_Queued_Message()

TAO_Asynch_Queued_Message::~TAO_Asynch_Queued_Message ( void )

virtual

Destructor.

◆ TAO_Asynch_Queued_Message() [2/3]

TAO_Asynch_Queued_Message::TAO_Asynch_Queued_Message	(	char *	buf,
		TAO_ORB_Core *	oc,
		size_t	size,
		const ACE_Time_Value &	abs_timeout,
		ACE_Allocator *	alloc,
		bool	is_heap_allocated
	)

protected

Constructor.

Parameters

buf	The buffer that needs to be sent on the wire. The buffer will be owned by this class. The buffer will be deleted when the destructor is called and hence the buffer should always come off the heap!
oc	The ORB Core
size	The size of the buffer <buf> that is being handed over.
abs_timeout	The time after which this message should be expired.
alloc	Allocator used for creating <this> object.

◆ TAO_Asynch_Queued_Message() [3/3]

TAO_Asynch_Queued_Message::TAO_Asynch_Queued_Message ( const TAO_Asynch_Queued_Message & )

private

The number of bytes in the buffer.

Member Function Documentation

◆ all_data_sent()

int TAO_Asynch_Queued_Message::all_data_sent ( void ) const

virtual

The number of bytes in the buffer.

Implements TAO_Queued_Message.

◆ bytes_transferred()

void TAO_Asynch_Queued_Message::bytes_transferred ( size_t & byte_count )

virtual

The number of bytes in the buffer.

Implements TAO_Queued_Message.

◆ clone()

TAO_Queued_Message * TAO_Asynch_Queued_Message::clone ( ACE_Allocator * alloc )

virtual

Note: No reason to believe why this would be called. But have it here for the sake of uniformity.

Implements TAO_Queued_Message.

◆ copy_if_necessary()

void TAO_Asynch_Queued_Message::copy_if_necessary ( const ACE_Message_Block * chain )

virtual

The number of bytes in the buffer.

Implements TAO_Queued_Message.

◆ destroy()

void TAO_Asynch_Queued_Message::destroy ( void )

virtual

The number of bytes in the buffer.

Implements TAO_Queued_Message.

◆ fill_iov()

void TAO_Asynch_Queued_Message::fill_iov	(	int	iovcnt_max,
		int &	iovcnt,
		iovec	iov[]
	)		const

virtual

The number of bytes in the buffer.

Implements TAO_Queued_Message.

◆ is_expired()

bool TAO_Asynch_Queued_Message::is_expired ( const ACE_Time_Value & now ) const

virtual

The number of bytes in the buffer.

Reimplemented from TAO_Queued_Message.

◆ message_length()

size_t TAO_Asynch_Queued_Message::message_length ( void ) const

virtual

The number of bytes in the buffer.

Implements TAO_Queued_Message.

◆ operator=()

void TAO_Asynch_Queued_Message::operator= ( const TAO_Asynch_Queued_Message & )

private

The number of bytes in the buffer.

◆ abs_timeout_

ACE_Time_Value TAO_Asynch_Queued_Message::abs_timeout_

private

The number of bytes in the buffer.

◆ buffer_

char* TAO_Asynch_Queued_Message::buffer_

private

The buffer containing the complete message.

◆ offset_

size_t TAO_Asynch_Queued_Message::offset_

private

The offset in the buffer.

Data up to offset has been sent already, only the [offset_,size_) range remains to be sent.

◆ size_

size_t const TAO_Asynch_Queued_Message::size_

private

The number of bytes in the buffer.
