                                       A extends java.lang.Exception

Execute this transformer, wrapping exceptions thrown by transformChecked(Object) into one of the passed exception classes.

Type Parameters:

Y - type of exception to throw.

Z - second type of exception to throw.

A - third type of exception to throw.

Parameters:

input - the input.

exnClass - class exception to throw.

exnClass2 - class exception to throw, can be null.

exnClass3 - class exception to throw, can be null.

Returns:

the result of this transformer.

Throws:

Y - if transformChecked(Object) throws an exception, it will be wrapped (if necessary) in an exception of class exnClass.

Z - if transformChecked(Object) throws an exception of class Z.

A - if transformChecked(Object) throws an exception of class A.
