                       java.util.Map<Node,java.lang.String> batchGroups)
Method Detail

prepare

public void prepare(java.util.Map conf,
                    TopologyContext context,
                    BatchOutputCollector batchCollector)
Specified by:
prepare in interface ITridentBatchBolt

execute

public void execute(BatchInfo batchInfo,
                    Tuple tuple)
Specified by:
execute in interface ITridentBatchBolt

finishBatch

public void finishBatch(BatchInfo batchInfo)
Specified by:
finishBatch in interface ITridentBatchBolt

initBatchState

public java.lang.Object initBatchState(java.lang.String batchGroup,
                                       java.lang.Object batchId)
Specified by:
initBatchState in interface ITridentBatchBolt

cleanup

public void cleanup()
Specified by:
cleanup in interface ITridentBatchBolt

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

getComponentConfiguration

public java.util.Map<java.lang.String,java.lang.Object> getComponentConfiguration()
Description copied from interface: 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

Specified by:
getComponentConfiguration in interface IComponent
