Interface RepeatOperations
- All Known Implementing Classes:
RepeatTemplate
,TaskExecutorRepeatTemplate
public interface RepeatOperations
The main interface providing access to batch operations. The batch client is
the
RepeatCallback
, where a single item or record is processed. The
batch behaviour, boundary conditions, transactions etc, are dealt with by the
RepeatOperations
in such as way that the client does not need to know
about them. The client may have access to framework abstractions, like
template data sources, but these should work the same whether they are in a
batch or not.- Author:
