Applies a flat select function to the detected pattern sequence.
Applies a flat select function to the detected pattern sequence. For each pattern sequence the provided PatternFlatSelectFunction is called. The pattern flat select function can produce an arbitrary number of resulting elements.
Additionally a timeout function is applied to partial event patterns which have timed out. For each partial pattern sequence the provided PatternFlatTimeoutFunction is called. The pattern timeout function can produce an arbitrary number of resulting timeout events.
You can get the stream of timeouted matches using DataStream.getSideOutput() on the DataStream resulting from the windowed operation with the same OutputTag.

Stream abstraction for CEP pattern detection. A pattern stream is a stream which emits detected pattern sequences as a map of events associated with their names. The pattern is detected using a org.apache.flink.cep.nfa.NFA. In order to process the detected sequences, the user has to specify a PatternSelectFunction or a PatternFlatSelectFunction.
