Method Details

getOrCreateTimeSeries

public DoubleCumulative.DoublePoint getOrCreateTimeSeries(List<LabelValue> labelValues)

Description copied from class: DoubleCumulative

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

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

Specified by:

getOrCreateTimeSeries in class DoubleCumulative

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.addDoubleCumulative(java.lang.String, io.opencensus.metrics.MetricOptions).

Returns:

a DoublePoint the value of single cumulative.

getDefaultTimeSeries

public DoubleCumulative.DoublePoint getDefaultTimeSeries()

Description copied from class: DoubleCumulative

Returns a DoublePoint for a cumulative with all labels not set, or default labels.

Specified by:

getDefaultTimeSeries in class DoubleCumulative

Returns:

a DoublePoint for a cumulative with all labels not set, or default labels.

removeTimeSeries

public void removeTimeSeries(List<LabelValue> labelValues)

Description copied from class: DoubleCumulative

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

Specified by:

removeTimeSeries in class DoubleCumulative

Parameters:

labelValues - the list of label values.

clear

public void clear()

Description copied from class: DoubleCumulative

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

Specified by:

clear in class DoubleCumulative

getMetricDescriptor

public MetricDescriptor getMetricDescriptor()

getMetric

@Nullable
