Interface Summary

Interface	Description
FieldExtractor<T>	This class will convert an object to an array of its parts.
FieldSet	Interface used by flat file input sources to encapsulate concerns of converting an array of Strings to Java native types.
FieldSetFactory	Factory interface for creating FieldSet instances.
LineAggregator<T>	Interface used to create string representing object.
LineTokenizer	Interface that is used by framework to split string obtained typically from a file into tokens.

Class Summary

Class	Description
AbstractLineTokenizer	Abstract class handling common concerns of various LineTokenizer implementations such as dealing with names and actual construction of FieldSet
BeanWrapperFieldExtractor<T>	This is a field extractor for a java bean.
DefaultFieldSet	Default implementation of FieldSet using Java primitive and standard types and utilities.
DefaultFieldSetFactory	Default implementation of FieldSetFactory with no special knowledge of the FieldSet required.
DelimitedLineAggregator<T>	A LineAggregator implementation that converts an object into a delimited list of strings.
DelimitedLineTokenizer	A LineTokenizer implementation that splits the input String on a configurable delimiter.
ExtractorLineAggregator<T>	An abstract LineAggregator implementation that utilizes a FieldExtractor to convert the incoming object to an array of its parts.
FixedLengthTokenizer	Tokenizer used to process data obtained from files with fixed-length format.
FormatterLineAggregator<T>	A LineAggregator implementation which produces a String by aggregating the provided item via the Formatter syntax.
PassThroughFieldExtractor<T>	FieldExtractor that just returns the original item.
PassThroughLineAggregator<T>	A LineAggregator implementation that simply calls Object.toString() on the given object
PatternMatchingCompositeLineTokenizer	A LineTokenizer implementation that stores a mapping of String patterns to delegate LineTokenizers.
Range	A class to represent ranges.
RangeArrayPropertyEditor	Property editor implementation which parses string and creates array of ranges.
RecursiveCollectionLineAggregator<T>	An implementation of LineAggregator that concatenates a collection of items of a common type with the system line separator.
RegexLineTokenizer	Line-tokenizer using a regular expression to filter out data (by using matching and non-matching groups).

Enum Summary

Enum	Description
Alignment	Deprecated Use FormatterLineAggregator.setFormat(java.lang.String) for alignment (See examples in FormatterLineAggregatorTests)

Exception Summary

Exception	Description
ConversionException
FlatFileFormatException	Exception indicating that some type of error has occurred while attempting to parse a line of input into tokens.
IncorrectLineLengthException	Exception indicating that the line size expected is different from what is expected.
IncorrectTokenCountException	Exception indicating that an incorrect number of tokens have been found while parsing a file.
