I'll one up y'all:
public class Sneak {
public static RuntimeException sneakyThrow(Throwable t) {
if ( t == null ) throw new NullPointerException("t");
Sneak.<RuntimeException>sneakyThrow0(t);
return null;
}
@SuppressWarnings("unchecked")
private static <T extends Throwable> void sneakyThrow0(Throwable t)
throws T {
throw (T)t;
}
There is absolutely no point in wrapping everything into a gazillion
layers of exceptions - that just results in 10 pages of stacktrace to
walk through. Preferably, all your classes throw the exceptions they
cause, but if interface restrictions are preventing you from sticking
'throws SQLException' in the appropriate places, use this. Don't wrap
unless there's a good reason for it. A good reason would be if e.g. a
database abstraction layer has its own 'DataSourceException', and a
specific implementation that works with files wraps
FileNotFoundExceptions in DataSourceExceptions. That's useful
wrapping. turning everything into 'MyRuntimeException' is a waste of
time.
Or, of course, use project lombok and add "@SneakyThrows
(SQLException.class)" to your method, which saves you a try/catch
block.
