Stream abstraction for CEP pattern detection.
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.
