getOrCreateTimeSeries

public LongGauge.NoopLongGauge.NoopLongPoint getOrCreateTimeSeries(java.util.List<LabelValue> labelValues)

Description copied from class: LongGauge

Creates a TimeSeries and returns a LongPoint if the specified labelValues is not already associated with this gauge, else returns an existing LongPoint.

It is recommended to keep a reference to the LongPoint instead of always calling this method for manual operations.

Specified by:

getOrCreateTimeSeries in class LongGauge

Parameters:

labelValues - the list of label values. The number of label values must be the same to that of the label keys passed to MetricRegistry.addLongGauge(java.lang.String, java.lang.String, java.lang.String, java.util.List<io.opencensus.metrics.LabelKey>).

Returns:

a LongPoint the value of single gauge.

getDefaultTimeSeries

public LongGauge.NoopLongGauge.NoopLongPoint getDefaultTimeSeries()

Description copied from class: LongGauge

Returns a LongPoint for a gauge with all labels not set, or default labels.

Specified by:

getDefaultTimeSeries in class LongGauge

Returns:

a LongPoint for a gauge with all labels not set, or default labels.

removeTimeSeries

public void removeTimeSeries(java.util.List<LabelValue> labelValues)

Description copied from class: LongGauge

Removes the TimeSeries from the gauge metric, if it is present. i.e. references to previous LongPoint objects are invalid (not part of the metric).

Specified by:

removeTimeSeries in class LongGauge

Parameters:

labelValues - the list of label values.

clear

public void clear()

Description copied from class: LongGauge

Removes all TimeSeries from the gauge metric. i.e. references to all previous LongPoint objects are invalid (not part of the metric).

Specified by:

clear in class LongGauge
