You can use the same type declarations with `str`, `float`, `bool` and many other complex data types.

Several of these are explored in the next chapters of the tutorial.

## Order matters { #order-matters }

When creating *path operations*, you can find situations where you have a fixed path.

    }

    // Maximum sizes for various SMB fields (based on protocol specifications)

 * references. It would not make sense to consider {@code null} and a non-null reference to be
 * "different representations of the same information", since one is distinguishable from
 * <i>missing</i> information and the other is not. The {@link #convert} method handles this null
 * behavior for all converters; implementations of {@link #doForward} and {@link #doBackward} are
 * guaranteed to never be passed {@code null}, and must never return {@code null}.

                    if (index == threadCount - 1) {
                        // Last thread wipes password
                        auth.secureWipePassword();
                    } else {
                        // Other threads try to read password
                        String pwd = auth.getPassword();
                        // Password might be null if already wiped

For active-active replication, automatic failover occurs on `GET/HEAD` operations if object or object version requested qualifies for replication and is missing on one site, but present on the other. This allows the applications to take full advantage of two-way replication even before the two sites get fully synced.
