  com.j_spaces.sadapter.datasource.BulkDataPersisterContext

public class BulkDataPersisterContext
extends Object

BulkDataPersisterContext an operation context that is accessible on mirror in BulkDataPersister.executeBulk(List) method.
BulkDataPersisterContext should be used to consolidate distributed transactions on the mirror side.
BulkDataPersisterContext is not accessible on any other space except mirror and not in any other method except BulkDataPersister.executeBulk(List)

Example of mirror implementation:

 public void executeBulk(List bulk) throws DataSourceException {
            BulkDataPersisterContext context = BulkDataPersisterContext.getCurrentContext();

           if (context.isTransactional()) {
               TransactionParticipantData txData = context.getTransactionData();


                long id = txData.getTransactionId();
                int participantId = txData.getParticipantId();
                int participantsCount = txData.getParticipantsCount();

                // add to pending transactions      
                ....


                // if all transactions parts arrived - execute bulk
                ....

            }
            else
            {
               //regular execution
               ....
            }

        }
