Method Summary

Modifier and Type	Method	Description
void	captureHeader(CSVReader reader)	Implementation of this method can grab the header line before parsing begins to use to map columns to bean properties.
protected void	loadUnadornedFieldMap(org.apache.commons.collections4.ListValuedMap<Class<?>,Field> fields)	This implementation intentionally does nothing in order to allow fuzzy matching in case there are no annotations at all in the class in question.

Constructor Details

FuzzyMappingStrategy

public FuzzyMappingStrategy()

Nullary constructor. Considered stable.

• FuzzyMappingStrategyBuilder

FuzzyMappingStrategy

public FuzzyMappingStrategy(boolean forceCorrectRecordLength)

Constructor to allow setting options for header name mapping. Not considered stable. As new options are introduced for the mapping strategy, they will be introduced here. You are encouraged to use FuzzyMappingStrategyBuilder.

Parameters:

forceCorrectRecordLength - If set, every record will be shortened or lengthened to match the number of headers

• FuzzyMappingStrategyBuilder

Method Details

loadUnadornedFieldMap

protected void loadUnadornedFieldMap(org.apache.commons.collections4.ListValuedMap<Class<?>,Field> fields)

This implementation intentionally does nothing in order to allow fuzzy matching in case there are no annotations at all in the class in question.

Overrides:

loadUnadornedFieldMap in class HeaderNameBaseMappingStrategy<T>

Parameters:

fields - A list of all non-synthetic fields in the bean to be processed

captureHeader

public void captureHeader(CSVReader reader)
                   throws IOException,
CsvRequiredFieldEmptyException

Description copied from interface: MappingStrategy

Implementation of this method can grab the header line before parsing begins to use to map columns to bean properties.

Specified by:

captureHeader in interface MappingStrategy<T>

Overrides:

captureHeader in class HeaderNameBaseMappingStrategy<T>

Parameters:

reader - The CSVReader to use for header parsing

Throws:

IOException - If parsing fails

CsvRequiredFieldEmptyException - If a field is required, but the header or column position for the field is not present in the input
