方法详细资料

getCurrentProcessingTime

long getCurrentProcessingTime()

Returns the current processing time.

getMetricGroup

org.apache.flink.metrics.MetricGroup getMetricGroup()

Returns the metric group for this Evictor. This is the same metric group that would be returned from RuntimeContext.getMetricGroup() in a user function.

You must not call methods that create metric objects (such as MetricGroup.counter(int) multiple times but instead call once and store the metric object in a field.

getCurrentWatermark

long getCurrentWatermark()

Returns the current watermark time.
