Class StringConverter
- Converter
public final class StringConverter
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.
