Method Details

throwUnchecked

public static <T> T throwUnchecked(Throwable ex,
 Class<T> ignoredReturnType)

Because this method throws an unchecked exception, when it is called in a method with a return type the compiler does not know the method is exiting, requiring a further line to return null or throw an unchecked exception directly. This generified method allows this to be avoided by tricking the compiler by adding a return statement as so:

     String someMethod() {
         try {
             somethingThatThrowsException();
         } catch (Exception e) {
             return throwUnchecked(e, null); // does not actually return, throws the exception
         }
     }
 

Parameters:

ex - The exception that will be thrown, unwrapped and unchecked

ignoredReturnType - trick to persuade the compiler that a method returns appropriately

Returns:

Never returns, always throws the passed in exception

throwUnchecked

public static void throwUnchecked(Throwable ex)

Parameters:

ex - The exception that will be thrown, unwrapped and unchecked

uncheck

public static <T> T uncheck(Callable<T> work,
 Class<T> returnType)

uncheck

public static void uncheck(Exceptions.RunnableWithException work)

renderStackTrace

public static String renderStackTrace(Throwable t)
