Method Detail

convertToModel

public Long convertToModel(Date value,
                           Class<? extends Long> targetType,
                           Locale locale)

Description copied from interface: Converter

Converts the given value from target type to source type.

A converter can optionally use locale to do the conversion.

A converter should in most cases be symmetric so chaining Converter.convertToPresentation(Object, Class, Locale) and Converter.convertToModel(Object, Class, Locale) should return the original value.

Specified by:

convertToModel in interface Converter<Date,Long>

Parameters:

value - The value to convert, compatible with the target type. Can be null

targetType - The requested type of the return value

locale - The locale to use for conversion. Can be null.

Returns:

The converted value compatible with the source type

convertToPresentation

public Date convertToPresentation(Long value,
                                  Class<? extends Date> targetType,
                                  Locale locale)

Description copied from interface: Converter

Converts the given value from source type to target type.
