Constructor Detail

ModuleNode

public ModuleNode(org.thales.punch.libraries.storm.api.NodeSettings boltConfig,
                  Serializable module,
                  org.thales.punch.libraries.storm.api.ITopologySettings topoConfig)

Parameters:

boltConfig - the bolt configuration

module - the module to be created

topoConfig - the topo configuration

Method Detail

setConvertors

public ModuleNode<T,V> setConvertors(IInputTupleConverter<T> in,
                                     IOutputTupleConverter<V> out)

Parameters:

in - the module input type

out - the module output type

Returns:

ModuleBolt<T,V>

prepare

public void prepare(Map stormConf,
                    org.apache.storm.task.TopologyContext context,
                    org.apache.storm.task.OutputCollector collector)

Prepare this bolt. Use this directly only for testing, and only after setting what you need in terms of configuration.

Specified by:

prepare in interface org.apache.storm.task.IBolt

Overrides:

prepare in class org.thales.punch.libraries.storm.api.BaseProcessingNode

process

public void process(org.apache.storm.tuple.Tuple tuple)

Specified by:

process in class org.thales.punch.libraries.storm.api.BaseProcessingNode

Parameters:

tuple - the input storm tuple.

declareOutputFields

public void declareOutputFields(org.apache.storm.topology.OutputFieldsDeclarer declarer)
