Thanks tillrohrmann. I put the test case in PatternTest.java as I didn't
think it warranted a separate class. See public void testPatternWithOrFilter()
in that class file.
I'll keep working on the auto format issue. I've had that for both PR's I
did. Any help with IntelliJ is appreciated. Seems like any file I touch gets
reformatted, but I can't find a way to turn that off with disabling the whole
style guide.
> Add or operator to CEP's pattern API
> ------------------------------------
>
> Key: FLINK-3319
> URL: https://issues.apache.org/jira/browse/FLINK-3319
> Project: Flink
> Issue Type: Improvement
> Components: CEP
> Affects Versions: 1.0.0
> Reporter: Till Rohrmann
> Assignee: Robert Thorman
> Priority: Minor
>
> Adding an {{or}} operator to CEP's pattern API would be beneficial. This
> would considerably extend the set of supported patterns. The {{or}} operator
> lets you define multiple succeeding pattern states for the next stage.
> {code}
> Pattern.begin("start").next("middle1").where(...).or("middle2").where(...)
> {code}
> In order to implement the {{or}} operator, one has to extend the {{Pattern}}
> class. Furthermore, the {{NFACompiler}} has to be extended to generate two
> resulting pattern states in case of an {{or}} operator.
