Class ParseDate

java.lang.Object

org.supercsv.cellprocessor.CellProcessorAdaptor

org.supercsv.cellprocessor.ParseDate

All Implemented Interfaces:

CellProcessor, StringCellProcessor

public class ParseDate
extends CellProcessorAdaptor
implements StringCellProcessor

Converts a String to a Date using the SimpleDateFormat class. If you want to convert from a Date to a String, use the FmtDate processor.

Some example date formats you can use are:
"dd/MM/yyyy" (parses a date formatted as "25/12/2011")
"dd-MMM-yy" (parses a date formatted as "25-Dec-11")
"yyyy.MM.dd.HH.mm.ss" (parses a date formatted as "2011.12.25.08.36.33"
"E, dd MMM yyyy HH:mm:ss Z" (parses a date formatted as "Tue, 25 Dec 2011 08:36:33 -0500")

This processor caters for lenient or non-lenient date interpretations (the default is false for constructors without a 'lenient' parameter). See DateFormat.setLenient(boolean) for more information.

If you don't wish to use the default Locale when parsing Dates (your data is formatted for a different Locale), then use the constructor that accepts a Locale.

Constructor Detail

ParseDate

public ParseDate(String dateFormat)

Constructs a new ParseDate processor which converts a String to a Date using the supplied date format. This constructor uses non-lenient Date interpretation.

Parameters:

dateFormat - the date format to use

Throws:

NullPointerException - if dateFormat is null

ParseDate

public ParseDate(String dateFormat,
         boolean lenient)

Constructs a new ParseDate processor which converts a String to a Date using the supplied date format.

Parameters:

dateFormat - the date format to use

lenient - whether date interpretation is lenient

Throws:

NullPointerException - if dateFormat is null

ParseDate

public ParseDate(String dateFormat,
         boolean lenient,
         Locale locale)

Constructs a new ParseDate processor which converts a String to a Date using the supplied date format and Locale.

Parameters:

dateFormat - the date format to use

lenient - whether date interpretation is lenient

locale - the Locale used to parse the date

Throws:

NullPointerException - if dateFormat or locale is null

ParseDate

public ParseDate(String dateFormat,
         DateCellProcessor next)

Constructs a new ParseDate processor which converts a String to a Date using the supplied date format, then calls the next processor in the chain. This constructor uses non-lenient Date interpretation.

Parameters:

dateFormat - the date format to use

next - the next processor in the chain

Throws:

NullPointerException - if dateFormat or next is null

ParseDate

public ParseDate(String dateFormat,
         boolean lenient,
         DateCellProcessor next)

Constructs a new ParseDate processor which converts a String to a Date using the supplied date format, then calls the next processor in the chain.

Parameters:

dateFormat - the date format to use

lenient - whether date interpretation is lenient

next - the next processor in the chain

Throws:

NullPointerException - if dateFormat or next is null

ParseDate

public ParseDate(String dateFormat,
         boolean lenient,
         Locale locale,
         DateCellProcessor next)

Constructs a new ParseDate processor which converts a String to a Date using the supplied date format and Locale, then calls the next processor in the chain.

Parameters:

dateFormat - the date format to use

lenient - whether date interpretation is lenient

locale - the Locale used to parse the date

next - the next processor in the chain

Throws:

NullPointerException - if dateFormat, locale, or next is null

Method Detail

execute

public Object execute(Object value,
             CsvContext context)

This method is invoked by the framework when the processor needs to process data or check constraints.

Specified by:

execute in interface CellProcessor

Throws:

SuperCsvCellProcessorException - if value is null, isn't a String, or can't be parsed to a Date
