Constructor Details

ConverterEnum

public ConverterEnum(Class<?> type,
 String locale,
 String writeLocale,
 Locale errorLocale)

Parameters:

type - The class of the type of the data being processed

locale - If not null or empty, specifies the locale used for converting locale-specific data types

writeLocale - If not null or empty, specifies the locale used for converting locale-specific data types for writing

errorLocale - The locale to use for error messages.

Method Details

convertToRead

public Object convertToRead(String value)
                     throws CsvDataTypeMismatchException

Description copied from interface: CsvConverter

Method for converting from a string to the proper data type of the destination field.

Parameters:

value - The string from the selected field of the CSV file. If the field is marked as required in the annotation, this value is guaranteed not to be null, empty or blank according to StringUtils.isBlank(java.lang.CharSequence)

Returns:

An Object representing the input data converted into the proper type

Throws:

CsvDataTypeMismatchException - If the input string cannot be converted into the proper type

convertToWrite

public String convertToWrite(Object value)

Description copied from class: AbstractCsvConverter

This implementation simply calls toString() on value. For complex types, overriding the toString() method in the type of the field in question would be an alternative to writing a conversion routine in a class derived from this one.

Specified by:

convertToWrite in interface CsvConverter

Overrides:

convertToWrite in class AbstractCsvConverter

Parameters:

value - The contents of the field currently being processed from the bean to be written. Can be null if the field is not marked as required.

Returns:

A string representation of the value of the field in question in the bean passed in, or an empty string if value is null
