DW Sample Replacement

Hi,
Is there are method the writer can be notified (via callbacks or by polling) that an unacknowledged sample has been replaced in the send_queue (in case the QOS allows this of course)?
I could not find any explicit indication for that in all of the Statuses for DataWriters (specifically the RELIABLE_WRITER_CACHE_CHANGED Status)

 

 Thank you,
Gal

Hi Gal,

Nowadays, it is not possible to do what you are asking with our current APIs.

I have filled an RFE requesting exactly that: being able to know when and what sample is replaced in the DataWriter's queue due to resource limits or history.

Kind regards,

Fran
