Trigger<Object,TimeWindow>	SlidingProcessingTimeWindows.getDefaultTrigger(StreamExecutionEnvironment env)
abstract Trigger<T,W>	WindowAssigner.getDefaultTrigger(StreamExecutionEnvironment env) Deprecated. the method is deprecated since Flink 1.19 because StreamExecutionEnvironment is unused. Please use getDefaultTrigger and override this method with an empty body instead. 1. If you override getDefaultTrigger(), the getDefaultTrigger() will be invoked and the getDefaultTrigger(StreamExecutionEnvironment env) won't be invoked. 2. If you don't override getDefaultTrigger(), the getDefaultTrigger(StreamExecutionEnvironment env) will be invoked in the default implementation of the getDefaultTrigger().
