Method Detail

getTimestampForFlow

public org.joda.time.Instant getTimestampForFlow(org.opennms.netmgt.flows.persistence.model.FlowDocument fd)

Description copied from class: SyntheticFlowTimestampPolicy

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.

Specified by:

getTimestampForFlow in class SyntheticFlowTimestampPolicy

getWatermark

public org.joda.time.Instant getWatermark()

Description copied from class: SyntheticFlowTimestampPolicy

Returns the estimation of the current watermark.

Specified by:

getWatermark in class SyntheticFlowTimestampPolicy

getCheckpointInstant

public org.joda.time.Instant getCheckpointInstant()

Description copied from class: SyntheticFlowTimestampPolicy

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.

Specified by:

getCheckpointInstant in class SyntheticFlowTimestampPolicy
