ItemStream	Marker interface defining a contract for periodically storing state and restoring from that state should an error occur.
ItemWriter	Basic interface for generic output operations.

Class Summary

AbstractItemReader	Base class for ItemReader implementations.
AbstractItemStreamItemReader	Base class for ItemReader implementations.
AbstractItemStreamItemWriter	Base class for ItemWriter implementations.
AbstractItemWriter	Abstract ItemWriter that allows for base classes to only implement the close method if they need it.
ExecutionContext	Object representing a context for an ItemStream.
ExecutionContextUserSupport	Facilitates assigning names to objects persisting data in ExecutionContext and generating keys for ExecutionContext based on the name.
ItemStreamSupport	Empty method implementation of ItemStream.

Exception Summary

ClearFailedException	Unchecked exception indicating that an error has occurred while trying to call ItemWriter.clear()
FlushFailedException	Unchecked exception indicating that an error has occurred while trying to call ItemWriter.flush()
ItemReaderException	A base exception class that all exceptions thrown from an ItemReader extend.
ItemStreamException	Exception representing any errors encountered while processing a stream.
ItemWriterException	A base exception class that all exceptions thrown from an ItemWriter extend.
MarkFailedException	An exception class thrown when an ItemReader fails to mark its current state for future retry.
NoWorkFoundException	Exception indicating that an ItemReader found no work to process while initializing.
ParseException	Exception indicating that an error has been encountered parsing io, typically from a file.
ReaderNotOpenException	Exception indicating that an ItemReader needed to be opened before read.
