  - declareOutputFields
```
public void declareOutputFields(OutputFieldsDeclarer declarer)
```
    Description copied from interface: IComponent
    
    Declare the output schema for all the streams of this topology.
    
    Parameters:
    
    declarer - this is used to declare output stream ids, output fields, and whether or not each output stream is a direct stream
