getOrCreateTimeSeries
public LongCumulative.LongPoint getOrCreateTimeSeries(java.util.List<LabelValue> labelValues)
Description copied from class:LongCumulative
Creates aTimeSeries
and returns aLongPoint
if the specifiedlabelValues
is not already associated with this cumulative, else returns an existingLongPoint
.It is recommended to keep a reference to the LongPoint instead of always calling this method for manual operations.
- Specified by:
getOrCreateTimeSeries
in classLongCumulative
- Parameters:
labelValues
- the list of label values. The number of label values must be the same to that of the label keys passed toMetricRegistry.addLongCumulative(java.lang.String, io.opencensus.metrics.MetricOptions)
.- Returns:
- a
LongPoint
the value of single cumulative.
-
getDefaultTimeSeries
public LongCumulative.LongPoint getDefaultTimeSeries()
Description copied from class:LongCumulative
Returns aLongPoint
for a cumulative with all labels not set, or default labels.- Specified by:
getDefaultTimeSeries
in classLongCumulative
- Returns:
- a
LongPoint
for a cumulative with all labels not set, or default labels.
-
removeTimeSeries
public void removeTimeSeries(java.util.List<LabelValue> labelValues)
Description copied from class:LongCumulative
Removes theTimeSeries
from the cumulative metric, if it is present. i.e. references to previousLongPoint
objects are invalid (not part of the metric).- Specified by:
removeTimeSeries
in classLongCumulative
- Parameters:
labelValues
- the list of label values.
-
clear
public void clear()
Description copied from class:LongCumulative
Removes allTimeSeries
from the cumulative metric. i.e. references to all previousLongPoint
objects are invalid (not part of the metric).- Specified by:
clear
in classLongCumulative
-
getMetricDescriptor
public MetricDescriptor getMetricDescriptor()
Description copied from interface:Meter
Provides aMetricDescriptor
.- Specified by:
getMetricDescriptor
in interfaceMeter
- Returns:
- a
MetricDescriptor
