declareOutputFieldsDescription copied from interface:IComponentDeclare the output schema for all the streams of this topology.- Specified by:
- declareOutputFieldsin interface- IComponent
- Parameters:
- declarer- this is used to declare output stream ids, output fields, and whether or not each output stream is a direct stream
 
- 
getComponentConfigurationDescription copied from interface:IComponentDeclare configuration specific to this component. Only a subset of the "topology.*" configs can be overridden. The component configuration can be further overridden when constructing the topology usingTopologyBuilder- Specified by:
