public DelegateClient(ResultParser<R> parser,
                      DiscoveryClient<String> inner)
```
    Creates an instance with a given ResultParser and a DiscoveryClient that produces untyped results
    
    Parameters:
    
    parser - the parser
    
    inner - the client

```
public List<R> submit(Query query)
               throws DiscoveryException,
                      InvalidResultException
```
    Submits a Query for remote execution and returns a list of typed results.
    Result parsing errors are only logged as long as some results are successfully parsed. Otherwise, the client flags the parsing errors as likely due to the parser itself.
    
    Specified by:
    
    submit in interface DiscoveryClient<R>
    
    Parameters:
    
    query - the query
    
    Returns:
    
    the results
    
    Throws:
    
    DiscoveryException - if the query cannot be submitted
    
    InvalidResultException - if the results cannot be parsed. Implementations may adopt different degrees of tolerance to parsing errors before raising this exception.
