示例1: declareOutputFields
import storm.trident.util.TridentUtils; //导入方法依赖的package包/类
@Override
public void declareOutputFields(OutputFieldsDeclarer declarer) {
Fields outFields = TridentUtils.getSingleOutputStreamFields(_delegate);
outFields = TridentUtils.fieldsConcat(new Fields("$id$"), outFields);
declarer.declareStream(_stream, outFields);
// try to find a way to merge this code with what's already done in TridentBoltExecutor
declarer.declareStream(_coordStream, true, new Fields("id", "count"));
}
示例2: newDRPCStream
import storm.trident.util.TridentUtils; //导入方法依赖的package包/类
private Stream newDRPCStream(DRPCSpout spout) {
// : consider adding a shuffle grouping after the spout to avoid so much routing of the args/return-info all over the place
// (at least until its possible to just pack bolt logic into the spout itself)
Node n = new SpoutNode(getUniqueStreamId(), TridentUtils.getSingleOutputStreamFields(spout), null, spout, SpoutNode.SpoutType.DRPC);
Stream nextStream = addNode(n);
// later on, this will be joined back with return-info and all the results
return nextStream.project(new Fields("args"));
}
