TimedOutPartialMatchHandler (Flink : Libraries : CEP 2.1.0 API)

Type Parameters:

IN - type of input elements

All Known Implementing Classes:

PatternTimeoutFlatSelectAdapter, PatternTimeoutSelectAdapter
```
@PublicEvolving
public interface TimedOutPartialMatchHandler<IN>
```
Enables handling timed out partial matches. It shall be used in a mixin style. If you need your PatternProcessFunction to be able to handle timed out partial matches implement this interface as well. Example:
```
 private class MyFunction extends PatternProcessFunction<IN, OUT> implements TimedOutPartialMatchHandler<IN> {

 }
 
```

- Method Detail
  - processTimedOutMatch
```
void processTimedOutMatch(Map<String,List<IN>> match,
                          PatternProcessFunction.Context ctx)
                   throws Exception
```
    Called for every timed out partial match (due to Pattern.within(Duration)). 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 {
    Parameters:
    
    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
    
    Throws:
    
    Exception - This method may throw exceptions. Throwing an exception will cause the operation to fail and may trigger recovery.
