Hello.

I can see the description of DelegatingItemReader in Appendix A( List of ItemReaders) as following

http://static.springframework.org/spring-batch/spring-batch-docs/reference/html/apa.html#d0e4963

"Extends AbstractMethodInvokingDelegator, which enables dynamically calling of a custom method of the injected object. Provides a convenient API for dynamic method invocation shielding subclasses from the low-level details and exception handling."


I guess this description is about ItemReaderAdapter, not DelegatingItemReader. (AggregateItemReader doesn't extend AbstractMethodInvokingDelegator)
