Class LocaleConvertUtilsBean

java.lang.Object
  extended by 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:

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).
