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.
