## Class LocaleConvertUtilsBean

- java.lang.Object
- - org.apache.commons.beanutils.locale.LocaleConvertUtilsBean

-     public class LocaleConvertUtilsBean
      extends 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, standard `LocaleConverter` 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 standard `LocaleConverter` instances with ones created with the one of the appropriate constructors. It's important that `LocaleConverter` should be registered for the specified locale and Class (or primitive type).
