public abstract class NestedCheckedException extends Exception
Handy class for wrapping checkedExceptions
with a root cause.This class is
abstract
to force the programmer to extend the class.getMessage
will include nested exception information;printStackTrace
and other like methods will delegate to the wrapped exception, if any.The similarity between this class and the
NestedRuntimeException
class is unavoidable, as Java forces these two classes to have different superclasses (ah, the inflexibility of concrete inheritance!).- 作者:
