- Method Detail
  - executeOrdered
```
byte[] executeOrdered(byte[] command,
                      MessageContext msgCtx)
```
    Method called to execute a request totally ordered. The message context contains a lot of information about the request, such as timestamp, nonces and sender. The code for this method MUST use the value of timestamp instead of relying on its own local clock, and nonces instead of trying to generated its own random values. This is important because this values are the same for all replicas, and therefore, ensure the determinism required in a replicated state machine.
    
    Parameters:
    
    command - the command issue by the client
    
    msgCtx - information related with the command
    
    Returns:
    
    the reply for the request issued by the client
