Method Detail

convertToModel

public Resource convertToModel(String value,
                               Class<? extends Resource> targetType,
                               Locale locale)
                        throws Converter.ConversionException

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<String,Resource>

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

Throws:

Converter.ConversionException - If the value could not be converted

convertToPresentation

public String convertToPresentation(Resource value,
                                    Class<? extends String> targetType,
