public abstract class BaseLocaleConverter extends Object implements LocaleConverter
The base class for all standart type locale-sensitive converters.
It has LocaleConverter and Converter implementations,
that convert an incoming locale-sensitive Object into an object of correspond type,
optionally using a default value or throwing a ConversionException
if a conversion error occurs.
