   org.apache.commons.beanutils.converters.AbstractConverter
      org.apache.commons.beanutils.converters.StringConverter

StringConverter
final public class StringConverter extends AbstractConverter (Code)
org.apache.commons.beanutils.Converter implementation that converts an incoming object into a java.lang.String object.

Note that ConvertUtils really is designed to do string->object conversions, and offers very little support for object->string conversions. The ConvertUtils/ConvertUtilsBean methods only select a converter to apply based upon the target type being converted to, and generally assume that the input is a string (by calling its toString method if needed).

This class is therefore just a dummy converter that converts its input into a string by calling the input object's toString method and returning that value.

It is possible to replace this converter with something that has a big if/else statement that selects behaviour based on the real type of the object being converted (or possibly has a map of converters, and looks them up based on the class of the input object). However this is not part of the existing ConvertUtils framework.
