- Method Detail
  - getTimestampForFlow
```
public abstract org.joda.time.Instant getTimestampForFlow(org.opennms.netmgt.flows.persistence.model.FlowDocument fd)
```
    Side effecting method that returns the timestamp for a flow document. A timestamp policy may track the observed flow documents in order to update its watermark estimation.
  - getWatermark
```
public abstract org.joda.time.Instant getWatermark()
```
    Returns the estimation of the current watermark.
  - getCheckpointInstant
```
public abstract org.joda.time.Instant getCheckpointInstant()
```
    Returns the time instant that is stored in FlowReader.CheckpointMark instances. Different timestamp policies may return different time instances, e.g. the current watermark or the maximum observed flow timestamp.
