Class HeaderColumnNameMappingStrategy<T>

java.lang.Object

com.opencsv.bean.AbstractMappingStrategy<String,String,ComplexFieldMapEntry<String,String,T>,T>

com.opencsv.bean.HeaderNameBaseMappingStrategy<T>

com.opencsv.bean.HeaderColumnNameMappingStrategy<T>

Type Parameters:

T - Type of the bean to be returned

All Implemented Interfaces:

MappingStrategy<T>

Direct Known Subclasses:

FuzzyMappingStrategy

public class HeaderColumnNameMappingStrategy<T>
extends HeaderNameBaseMappingStrategy<T>

Maps data to objects using the column names in the first row of the CSV file as reference. This way the column order does not matter.

Constructor Detail

HeaderColumnNameMappingStrategy

public HeaderColumnNameMappingStrategy()

Default constructor. Considered stable.

HeaderColumnNameMappingStrategyBuilder

HeaderColumnNameMappingStrategy

public HeaderColumnNameMappingStrategy(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 HeaderColumnNameMappingStrategyBuilder.

Parameters:

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

HeaderColumnNameMappingStrategyBuilder

Method Detail

loadAnnotatedFieldMap

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

Creates a map of annotated fields in the bean to be processed.

This method is called by AbstractMappingStrategy.loadFieldMap() when at least one relevant annotation is found on a member variable.

Overrides:

loadAnnotatedFieldMap in class AbstractMappingStrategy<String,String,ComplexFieldMapEntry<String,String,T>,T>

Parameters:

fields - A list of fields annotated with a binding annotation in the bean to be processed

getBindingAnnotations

protected Set<Class<? extends Annotation>> getBindingAnnotations()

Returns a set of the annotations that are used for binding in this mapping strategy.

In this mapping strategy, those are currently:

• CsvBindByName
• CsvCustomBindByName
• CsvBindAndJoinByName
• CsvBindAndSplitByName

Overrides:

getBindingAnnotations in class AbstractMappingStrategy<String,String,ComplexFieldMapEntry<String,String,T>,T>

Returns:

Annotations of the sort CsvBindByName or CsvBindByPosition that are relevant for binding input fields to bean members in this mapping strategy
