Interface Summary

Interface	Description
ChunkProcessor<I>	Interface defined for processing Chunks.
ChunkProvider<T>	Interface for providing Chunks to be processed, used by the ChunkOrientedTasklet
KeyGenerator	Interface for defining keys to uniquely identify items.

Class Summary

Class	Description
BatchRetryTemplate	A special purpose retry template that deals specifically with multi-valued stateful retry.
Chunk<W>	Encapsulation of a list of items to be processed and possibly a list of failed items to be skipped.
ChunkMonitor	Manage the offset data between the last successful commit and updates made to an input chunk.
ChunkMonitor.ChunkMonitorData
ChunkOrientedTasklet<I>	A Tasklet implementing variations on read-process-write item handling.
DefaultItemFailureHandler	Default implementation of the ItemListenerSupport class that writes all exceptions via commons logging.
FaultTolerantChunkProcessor<I,O>	FaultTolerant implementation of the ChunkProcessor interface, that allows for skipping or retry of items that cause exceptions during writing.
FaultTolerantChunkProvider<I>	FaultTolerant implementation of the ChunkProcessor interface, that allows for skipping or retry of items that cause exceptions during reading or processing.
SimpleChunkProcessor<I,O>	Simple implementation of the ChunkProcessor interface that handles basic item writing and processing.
SimpleChunkProvider<I>	Simple implementation of the ChunkProvider interface that does basic chunk providing from an ItemReader.
SimpleRetryExceptionHandler	An ExceptionHandler that is aware of the retry context so that it can distinguish between a fatal exception and one that can be retried.
SkipWrapper<T>	Wrapper for an item and its exception if it failed processing.

Exception Summary

Exception	Description
ForceRollbackForWriteSkipException	Fatal exception to be thrown when a rollback must be forced, typically after catching an exception that otherwise would not cause a rollback.
