public void declareOutputFields(OutputFieldsDeclarer declarer)
IComponent
Declare the output schema for all the streams of this topology.
declarer
- this is used to declare output stream ids, output fields, and whether or not each output stream is a direct streampublic void execute(Tuple input, BasicOutputCollector collector)
IBasicBolt
Process the input tuple and optionally emit new tuples based on the input tuple.
All acking is managed for you. Throw a FailedException if you want to fail the tuple.
public Map<String,Object> getComponentConfiguration()
IComponent
Declare 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 using TopologyBuilder
