Classes

Class	Description
AbstractFileItemWriter<T>	Base class for item writers that write data to a file or stream.
AbstractItemCountingItemStreamItemReader<T>	Abstract superclass for ItemReaders that supports restart by storing item count in the ExecutionContext (therefore requires item ordering to be preserved between runs).
AbstractItemStreamItemReader<T>	Base class for ItemReader implementations.
AbstractItemStreamItemWriter<T>	Base class for ItemWriter implementations.
ClassifierCompositeItemProcessor<I,O>	Calls one of a collection of ItemProcessors, based on a router pattern implemented through the provided Classifier.
ClassifierCompositeItemWriter<T>	Calls one of a collection of ItemWriters for each item, based on a router pattern implemented through the provided Classifier.
CompositeItemProcessor<I,O>	Composite ItemProcessor that passes the item through a sequence of injected ItemTransformers (return value of previous transformation is the entry value of the next). Note the user is responsible for injecting a chain of ItemProcessors that conforms to declared input and output types.
CompositeItemReader<T>	Composite reader that delegates reading to a list of ItemStreamReaders.
CompositeItemStream	Simple ItemStream that delegates to a list of other streams.
CompositeItemWriter<T>	Calls a collection of ItemWriters in fixed-order sequence. The implementation is thread-safe if all delegates are thread-safe.
IteratorItemReader<T>	An ItemReader that pulls data from a Iterator or Iterable using the constructors.
ListItemReader<T>	An ItemReader that pulls data from a list.
ListItemWriter<T>	Item writer that writes items to a List.
PassThroughItemProcessor<T>	Simple ItemProcessor that does nothing - simply passes its argument through to the caller.
ScriptItemProcessor<I,O>	ItemProcessor implementation that passes the current item to process to the provided script.
SingleItemPeekableItemReader<T>	A PeekableItemReader that allows the user to peek one item ahead.
SynchronizedItemReader<T>	This is an ItemReader decorator with a synchronized ItemReader.read() method.
SynchronizedItemStreamReader<T>	This is a simple ItemStreamReader decorator with a synchronized ItemReader.read() method - which makes a non-thread-safe ItemReader thread-safe.
SynchronizedItemStreamWriter<T>	An ItemStreamWriter decorator with a synchronized write() method.
SynchronizedItemWriter<T>	This is an ItemWriter decorator with a synchronized ItemWriter.write(org.springframework.batch.item.Chunk<? extends T>) method.
