Returns the format used by #convertToPresentation(Byte, Class, Locale) and convertToModel(String, Class, Locale).

Overrides:

getFormat in class AbstractStringToNumberConverter<Byte>

Parameters:

locale - The locale to use

Returns:

A NumberFormat instance

convertToModel

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

Deprecated.

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.

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

getModelType

public Class<Byte> getModelType()

Deprecated.

Description copied from interface: Converter

The source type of the converter. Values of this type can be passed to Converter.convertToPresentation(Object, Class, Locale).

Returns:

The source type
