Method Detail

convert

protected Object convert(String value)
                  throws CsvDataTypeMismatchException

Description copied from class: AbstractBeanField

Method for converting from a string to the proper datatype of the destination field. This method must be specified in all non-abstract derived classes.

Specified by:

convert in class AbstractBeanField<T>

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

protected String convertToWrite(Object value)
                         throws CsvDataTypeMismatchException

This method takes the current value of the field in question in the bean passed in and converts it to a string. It works for all of the primitives, wrapped primitives, String, BigDecimal, and BigInteger.

Overrides:

convertToWrite in class AbstractBeanField<T>

Parameters:

value - The contents of the field currently being processed from the bean to be written. Can be null.

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

Throws:

CsvDataTypeMismatchException - If there is an error converting value to a string
