Detailed Description

Constructor & Destructor Documentation

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

(

void

)

[virtual]

Destructor.

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.

ACE_Time_Value TAO_Asynch_Queued_Message::abs_timeout_ [private]

char* TAO_Asynch_Queued_Message::buffer_ [private]

The buffer containing the complete message.

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_t const TAO_Asynch_Queued_Message::size_ [private]

The number of bytes in the buffer.
