Package org.springframework.batch.repeat
Interface RepeatOperations
- All Known Implementing Classes:
RepeatTemplate
,TaskExecutorRepeatTemplate
- Functional Interface:
- This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
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:
