      Description

      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.

      Pattern.begin("start").where(...).followedBy("middle").notFollowedBy("not").where(...).notNext("not2").where(...)
