Examples of org.springframework.batch.core.step.tasklet.TaskletStep$ChunkTransactionCallback

org.springframework.batch.core.step.tasklet.TaskletStep
A callback for the transactional work inside a chunk. Also detects failures in the transaction commit and rollback, only panicking if the transaction status is unknown (i.e. if a commit failure leads to a clean rollback then we assume the state is consistent). @author Dave Syer
