Constructor Details

DateLocaleConverter

public DateLocaleConverter()

Create a LocaleConverter that will throw a ConversionException if a conversion error occurs. The locale is the default locale for this instance of the Java Virtual Machine and an unlocalized pattern is used for the convertion.

DateLocaleConverter

public DateLocaleConverter(boolean locPattern)

Create a LocaleConverter that will throw a ConversionException if a conversion error occurs. The locale is the default locale for this instance of the Java Virtual Machine.

Parameters:

locPattern - Indicate whether the pattern is localized or not

DateLocaleConverter

public DateLocaleConverter(Locale locale)

Create a LocaleConverter that will throw a ConversionException if a conversion error occurs. An unlocalized pattern is used for the convertion.

Parameters:

locale - The locale

DateLocaleConverter

public DateLocaleConverter(Locale locale,
 boolean locPattern)

Create a LocaleConverter that will throw a ConversionException if a conversion error occurs.

Parameters:

locale - The locale

locPattern - Indicate whether the pattern is localized or not

DateLocaleConverter

public DateLocaleConverter(Locale locale,
 String pattern)

Create a LocaleConverter that will throw a ConversionException if a conversion error occurs. An unlocalized pattern is used for the convertion.

Parameters:

locale - The locale

pattern - The convertion pattern

DateLocaleConverter

public DateLocaleConverter(Locale locale,
 String pattern,
 boolean locPattern)

Create a LocaleConverter that will throw a ConversionException if a conversion error occurs.

Parameters:

locale - The locale

pattern - The convertion pattern

locPattern - Indicate whether the pattern is localized or not

DateLocaleConverter

public DateLocaleConverter(Object defaultValue)

Create a LocaleConverter that will return the specified default value if a conversion error occurs. The locale is the default locale for this instance of the Java Virtual Machine and an unlocalized pattern is used for the convertion.

Parameters:

defaultValue - The default value to be returned

DateLocaleConverter

public DateLocaleConverter(Object defaultValue,
 boolean locPattern)

Method Details

initDefaultChars

private static String initDefaultChars()

This method is called at class initialization time to define the value for constant member DEFAULT_PATTERN_CHARS. All other methods needing this data should just read that constant.

convertLocalizedPattern

private String convertLocalizedPattern(String localizedPattern,
 Locale locale)

Convert a pattern from a localized format to the default format.

Parameters:

localizedPattern - The pattern in 'local' symbol format

locale - The locale

Returns:

pattern in 'default' symbol format

convertPattern

private String convertPattern(String pattern,
 String fromChars,
 String toChars)

Converts a Pattern from one character set to another.

isLenient

public boolean isLenient()

Returns whether date formatting is lenient.

Returns:

true if the DateFormat used for formatting is lenient

See Also:

• DateFormat.isLenient()

parse

protected Object parse(Object value,
 String pattern)
                throws ParseException

Convert the specified locale-sensitive input object into an output object of the specified type.

Specified by:

parse in class BaseLocaleConverter

Parameters:

value - The input object to be converted

pattern - The pattern is used for the convertion

Returns:

the converted Date value

Throws:

ConversionException - if conversion cannot be performed successfully

ParseException - if an error occurs parsing

setLenient

public void setLenient(boolean lenient)

Specify whether or not date-time parsing should be lenient.

Parameters:

lenient - true if the DateFormat used for formatting should be lenient
