示例1: execute
import org.apache.storm.tuple.Tuple; //導入方法依賴的package包/類
@Override
public void execute(Tuple tuple) {
Object obj = tuple.getValue(0);
long count = tuple.getLong(1);
int source = tuple.getSourceTask();
Map<Integer, Long> subCounts = counts.get(obj);
if (subCounts == null) {
subCounts = new HashMap<Integer, Long>();
counts.put(obj, subCounts);
}
//Update the current count for this object
subCounts.put(source, count);
//Output the sum of all the known counts so for this key
long sum = 0;
for (Long val: subCounts.values()) {
sum += val;
}
collector.emit(new Values(obj, sum));
