PatternTimeoutFlatSelectAdapter

public PatternTimeoutFlatSelectAdapter(PatternFlatSelectFunction<IN,OUT> flatSelectFunction,
                                       PatternFlatTimeoutFunction<IN,T> flatTimeoutFunction,
                                       org.apache.flink.util.OutputTag<T> timedOutPartialMatchesTag)

方法详细资料

open

public void open(org.apache.flink.configuration.Configuration parameters)
          throws Exception

指定者:

open 在接口中 org.apache.flink.api.common.functions.RichFunction

覆盖:

open 在类中 PatternFlatSelectAdapter<IN,OUT>

抛出:

Exception

close

public void close()
           throws Exception

指定者:

close 在接口中 org.apache.flink.api.common.functions.RichFunction

覆盖:

close 在类中 PatternFlatSelectAdapter<IN,OUT>

抛出:

Exception

processTimedOutMatch

public void processTimedOutMatch(Map<String,List<IN>> match,
                                 PatternProcessFunction.Context ctx)
                          throws Exception

从接口复制的说明: TimedOutPartialMatchHandler

Called for every timed out partial match (due to Pattern.within(Time)). It enables custom handling, e.g. one can emit the timed out results through a side output:

{@code
 private final OutputTag timedOutPartialMatchesTag = ...

 private class MyFunction extends PatternProcessFunction implements TimedOutPartialMatchHandler {

指定者:

processTimedOutMatch 在接口中 TimedOutPartialMatchHandler<IN>

参数:

match - map containing the timed out partial match. Events are identified by their names.

ctx - enables access to time features and emitting results through side outputs

抛出:

Exception - This method may throw exceptions. Throwing an exception will cause the operation to fail and may trigger recovery.
