Method Summary

All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method	Description
`default RelativeClock`	`getInputActivityClock()`	Returns a `RelativeClock` that hides periods when input was not active and `WatermarkGenerator` could not have been executed due to execution being blocked by the runtime.
`org.apache.flink.metrics.MetricGroup`	`getMetricGroup()`	Returns the metric group for the context in which the created `WatermarkGenerator` is used.

- Method Detail
  - getMetricGroup
```
org.apache.flink.metrics.MetricGroup getMetricGroup()
```
    Returns the metric group for the context in which the created WatermarkGenerator is used.
    Instances of this class can be used to register new metrics with Flink and to create a nested hierarchy based on the group names. See MetricGroup for more information for the metrics system.

  - getInputActivityClock
```
default RelativeClock getInputActivityClock()
```
    Returns a RelativeClock that hides periods when input was not active and WatermarkGenerator could not have been executed due to execution being blocked by the runtime. For example a backpressure or watermark alignment blocking the progress.
    The default implementation that returns SystemClock is only for 1.19 and 1.20 release to keep binary compatibility of the user's code.
