locale- The locale to useReturns:
A NumberFormat instance

convertToModel
public BigInteger convertToModel(String value, Class<? extends BigInteger> targetType, Locale locale) throws Converter.ConversionExceptionDescription copied from interface:
ConverterConverts 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 chainingConverter.convertToPresentation(Object, Class, Locale)andConverter.convertToModel(Object, Class, Locale)should return the original value.Parameters:
value- The value to convert, compatible with the target type. Can be nulltargetType- The requested type of the return valuelocale- 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<BigInteger> getModelType()Description copied from interface:
ConverterThe source type of the converter. Values of this type can be passed to
Converter.convertToPresentation(Object, Class, Locale).Returns:
The source type
