示例1: executeOnCollections
import org.apache.flink.api.common.functions.util.CopyingIterator; //導入依賴的package包/類
@Override
protected List<OUT> executeOnCollections(List<IN> inputData, RuntimeContext ctx, ExecutionConfig executionConfig) throws Exception {
MapPartitionFunction<IN, OUT> function = this.userFunction.getUserCodeObject();
FunctionUtils.setFunctionRuntimeContext(function, ctx);
FunctionUtils.openFunction(function, this.parameters);
ArrayList<OUT> result = new ArrayList<OUT>(inputData.size() / 4);
TypeSerializer<IN> inSerializer = getOperatorInfo().getInputType().createSerializer(executionConfig);
TypeSerializer<OUT> outSerializer = getOperatorInfo().getOutputType().createSerializer(executionConfig);
CopyingIterator<IN> source = new CopyingIterator<IN>(inputData.iterator(), inSerializer);
CopyingListCollector<OUT> resultCollector = new CopyingListCollector<OUT>(result, outSerializer);
function.mapPartition(source, resultCollector);
result.trimToSize();
FunctionUtils.closeFunction(function);
return result;
