------------------------------------
Summary: Add not operator to CEP's pattern API
Key: FLINK-3320
URL: https://issues.apache.org/jira/browse/FLINK-3320
Project: Flink
Issue Type: Improvement
Components: CEP
Affects Versions: 1.0.0
Reporter: Till Rohrmann
Priority: Minor
Currently, CEP's pattern API is lacking a {{not}} operator which would you
allow to define which events must not occur in a matched pattern. It would be
beneficial to add this operator in order to increase the set of supported
patterns.
{code}
Pattern.begin("start").where(...).followedBy("middle").notFollowedBy("not").where(...).notNext("not2").where(...)
{code}
