Method Summary

Modifier and Type	Method	Description
void	declareOutputFields(OutputFieldsDeclarer declarer)	Declare the output schema for all the streams of this topology.
void	execute(TupleWindow inputWindow)	Process the tuple window and optionally emit new tuples based on the tuples in the input window.
void	prepare(Map<String,Object> topoConf, TopologyContext context, OutputCollector collector)	This is similar to the IBolt.prepare(Map, TopologyContext, OutputCollector) except that while emitting, the tuples are automatically anchored to the tuples in the inputWindow.

Method Details

prepare

public void prepare(Map<String,Object> topoConf,
 TopologyContext context,
 OutputCollector collector)

Description copied from interface: IWindowedBolt

This is similar to the IBolt.prepare(Map, TopologyContext, OutputCollector) except that while emitting, the tuples are automatically anchored to the tuples in the inputWindow.

Specified by:

prepare in interface IWindowedBolt

Overrides:

prepare in class BaseWindowedBolt

execute

public void execute(TupleWindow inputWindow)

Description copied from interface: IWindowedBolt

Process the tuple window and optionally emit new tuples based on the tuples in the input window.

declareOutputFields

public void declareOutputFields(OutputFieldsDeclarer declarer)

Description copied from interface: IComponent

Declare the output schema for all the streams of this topology.

Specified by:

declareOutputFields in interface IComponent

Overrides:

declareOutputFields in class BaseWindowedBolt

Parameters:

declarer - this is used to declare output stream ids, output fields, and whether or not each output stream is a direct stream
