Type Parameters:

T - The expected type

Parameters:

t - The Throwable to throw.

Returns:

nothing actually will be returned from this method because it rethrows the specified exception. Making this method return an arbitrary type makes the caller method easier as they do not have to add a return statement after calling this method.
