getOrCreateTimeSeries

public LongCumulative.NoopLongCumulative.NoopLongPoint getOrCreateTimeSeries(List<LabelValue> labelValues)

Description copied from class: LongCumulative

Creates a TimeSeries and returns a LongPoint if the specified labelValues is not already associated with this cumulative, 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 LongCumulative

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.addLongCumulative(String, MetricOptions).

Returns:

a LongPoint the value of single cumulative.

getDefaultTimeSeries

public LongCumulative.NoopLongCumulative.NoopLongPoint getDefaultTimeSeries()

Description copied from class: LongCumulative

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

Specified by:

getDefaultTimeSeries in class LongCumulative

Returns:

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

removeTimeSeries

public void removeTimeSeries(List<LabelValue> labelValues)

Description copied from class: LongCumulative

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

Specified by:

removeTimeSeries in class LongCumulative

Parameters:

labelValues - the list of label values.

clear

public void clear()

Description copied from class: LongCumulative

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

Specified by:

clear in class LongCumulative
