----------------------------------------
dawidwys opened a new pull request #7280: [FLINK-10596][cep] Introduced
PatternProcessFunction with access to timerService
URL: https://github.com/apache/flink/pull/7280
## What is the purpose of the change
This PR introduces `PatternProcessFunction`, which implements
`RichFunction`, gives access to timestamp of match as well as access to
`currentProcessingTime` from `TimerService`. There was introduced an additional
optional interface that user can implement, which enables handling timed out
partial matches as well (`TimedOutPartialMatchHandler`).
Those features(rich interface, access to timer service) are needed for
integration with SQL to support UDFs and time operations.
## Brief change log
- Introduced `PatternProcessFunction`
- Introduced `TimedOutPartialMatchHandler`
- mentioned interfaces have access to `TimerContext`
- addded adapters from old interfaces to `PatternProcessFunction`
- changed `CepOperator` to work only with process function
## Verifying this change
- all existing tests pass - support for old interfaces
- `org.apache.flink.cep.operator.CepOperatorContextTest`
