# 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.
