示例1: prepare
import storm.trident.planner.processor.TridentContext; //导入依赖的package包/类
@Override
public void prepare(Map conf, TopologyContext context, TridentContext tridentContext) {
this.conf = conf;
this.topologyContext = context;
List<TridentTuple.Factory> parents = tridentContext.getParentTupleFactories();
if (parents.size() != 1) {
throw new RuntimeException("Aggregation related operation can only have one parent");
}
Long maxTuplesCacheSize = getWindowTuplesCacheSize(conf);
this.tridentContext = tridentContext;
collector = new FreshCollector(tridentContext);
projection = new TridentTupleView.ProjectionFactory(parents.get(0), inputFields);
windowStore = windowStoreFactory.create();
windowTaskId = windowId + WindowsStore.KEY_SEPARATOR + topologyContext.getThisTaskId() + WindowsStore.KEY_SEPARATOR;
windowTriggerInprocessId = getWindowTriggerInprocessIdPrefix(windowTaskId);
tridentWindowManager = storeTuplesInStore ?
new StoreBasedTridentWindowManager(windowConfig, windowTaskId, windowStore, aggregator, tridentContext.getDelegateCollector(), maxTuplesCacheSize, inputFields)
: new InMemoryTridentWindowManager(windowConfig, windowTaskId, windowStore, aggregator, tridentContext.getDelegateCollector());
tridentWindowManager.prepare();
}
