Detailed Description

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

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
contentsThe message block chain that must be sent.
allocAllocator used for creating this object.
timeoutThe 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
bufThe 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!
ocThe ORB Core
sizeThe size of the buffer <buf> that is being handed over.
abs_timeoutThe time after which this message should be expired.
allocAllocator used for creating <this> object.

Member Data Documentation

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.
