public class LocaleConvertUtilsBean extends java.lang.Object
Utility methods for converting locale-sensitive String scalar values to objects of the specified Class, String arrays to arrays of the specified Class and object to locale-sensitive String scalar value.
This class provides the implementations used by the static utility methods in
LocaleConvertUtils
.The actual
LocaleConverter
instance to be used can be registered for each possible destination Class. Unless you override them, standardLocaleConverter
instances are provided for all of the following destination Classes:- java.lang.BigDecimal
- java.lang.BigInteger
- byte and java.lang.Byte
- double and java.lang.Double
- float and java.lang.Float
- int and java.lang.Integer
- long and java.lang.Long
- short and java.lang.Short
- java.lang.String
- java.sql.Date
- java.sql.Time
- java.sql.Timestamp
For backwards compatibility, the standard locale converters for primitive types (and the corresponding wrapper classes). If you prefer to have another
LocaleConverter
thrown instead, replace the standardLocaleConverter
instances with ones created with the one of the appropriate constructors. It's important thatLocaleConverter
should be registered for the specified locale and Class (or primitive type).- Since:

Constructor Summary
Constructors Constructor Description LocaleConvertUtilsBean()
Makes the state by default (deregisters all converters for all locales) and then registers default locale converters.
