  - ### Method Summary

    All Methods Instance Methods Concrete Methods
    Modifier and Type | Method and 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 Detail

    - #### 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
