Interface	Description
BufferedReaderFactory	A factory strategy for custom extensions of BufferedReader allowing customisation of the standard behaviour of the java.io variety.
FlatFileFooterCallback	Callback interface for writing a footer to a file.
FlatFileHeaderCallback	Callback interface for writing a header to a file.
LineCallbackHandler	Callback interface for handling a line from file.
LineMapper<T>	Interface for mapping lines (strings) to domain objects typically used to map lines read from a file to domain objects on a per line basis.
ResourceAwareItemReaderItemStream<T>	Interface for ItemReaders that implement ItemStream and read input from Resource.
ResourceAwareItemWriterItemStream<T>	Interface for ItemWriters that implement ItemStream and write output to Resource.
ResourceSuffixCreator	Strategy interface for translating resource index into unique filename suffix.

Class Summary

Class	Description
DefaultBufferedReaderFactory
FlatFileItemReader<T>	Restartable ItemReader that reads lines from input FlatFileItemReader.setResource(Resource).
FlatFileItemWriter<T>	This class is an item writer that writes data to a file or stream.
MultiResourceItemReader<T>	Reads items from multiple resources sequentially - resource list is given by MultiResourceItemReader.setResources(Resource[]), the actual reading is delegated to MultiResourceItemReader.setDelegate(ResourceAwareItemReaderItemStream).
MultiResourceItemWriter<T>	Wraps a ResourceAwareItemWriterItemStream and creates a new output resource when the count of items written in current resource exceeds MultiResourceItemWriter.setItemCountLimitPerResource(int).
ResourcesItemReader	ItemReader which produces Resource instances from an array.
SimpleBinaryBufferedReaderFactory	A BufferedReaderFactory useful for reading simple binary (or text) files with no line endings, such as those produced by mainframe copy books.
SimpleResourceSuffixCreator	Trivial implementation of ResourceSuffixCreator that uses the index itself as suffix, separated by dot.

Exception Summary

Exception	Description
FlatFileParseException	Exception thrown when errors are encountered parsing flat files.
NonTransientFlatFileException	Exception thrown when errors are encountered with the underlying resource.
