How do i know the no. of transaction doDML will perform?

Question

Hi,
In my application, i am using custom java data source implementation methodology as per the document. I have to fetch records from a service and to populate it to view object and to post the records which belongs to current transaction, to service. I am able to populate data into view object but have an issue while getting the dirty records and post it to my service.
Requirement scenario is explained below.
1. User has done changes in some of the fetched records, added some new records and deleted some records.
2. When he press save, because of the execution of commit operation, control will come to doDML method as many times as it needs based on the no. of transactions.
3. My requirement is to identify all the records and to pack it and to send it to my service at a single shot.
I need some place where i should be able to identify how many times doDML method belongs to a particular entity object will be called, so that i can decide when to call my service. For example, i have done 2 insert and 1 delete, as per the framework, doDML will be called 3 times. I need to capture the record details during these 3 times and to call my service only at 3rd time.
Any idea on how to achive this??
Thanks in advance.

Answer 1

This will not help srinidhi.. Because if i perform my service call after the control has come out from doDML() method, dirty transaction will become undirty. So even if i get any error from my service while posting data to it, next time if user corrects it and click on save, it will not come to doDML() method itself. So i should perform my service call inside the doDML() itself.
