Method Detail

rethrowAsException

public static Exception rethrowAsException(Throwable e)
                                    throws Exception

Rethrows the given Throwable, allowing the caller to declare that it throws Exception. This is useful when your callers have nothing reasonable they can do when a Throwable is thrown. This is declared to return Exception so it can be used in a throw clause:

 try {
   doSomething();
 } catch (Throwable e} {
   throw Throwables.rethrowAsException(e);
 }
 doSomethingLater();
 

Parameters:

e - exception to rethrow

Returns:

does not return anything

Throws:

Exception
