- Method Detail
  - getResource
```
Resource getResource()
```
    Returns the metric Resource.
    The Resource is configured via SdkMeterProviderBuilder.setResource(Resource).
  - getInstrumentationScopeInfo
```
InstrumentationScopeInfo getInstrumentationScopeInfo()
```
    Returns the metric InstrumentationScopeInfo.
    The InstrumentationScopeInfo is determined from the options used when MeterBuilder.build()ing the Meter.
  - getName
```
java.lang.String getName()
```
    Returns the metric name.
    The metric name is typically the instrument name, but may be optionally overridden by a View.
  - getDescription
```
java.lang.String getDescription()
```
    Returns the metric description.
    The metric name is typically the instrument description, but may be optionally overridden by a View.
  - getUnit
```
java.lang.String getUnit()
```
    Returns the metric unit.
  - getType
```
MetricDataType getType()
```
    Returns the type of this metric.
  - getData
```
Data<?> getData()
```
    Returns the unconstrained metric data.
    Most will instead prefer to access the constrained metric data after first checking the getType():
    // if (metricData.getType() == MetricDataType.LONG_SUM) { // SumData<LongPointData> sumData = metricData.getLongSumData(); // ... // Process long sum data // }

  - isEmpty
```
default boolean isEmpty()
```
    Returns true if there are no points associated with this metric.
  - getDoubleGaugeData
```
default GaugeData<DoublePointData> getDoubleGaugeData()
```
    Returns the double GaugeData if type is MetricDataType.DOUBLE_GAUGE, otherwise a default empty data.
  - getLongGaugeData
```
default GaugeData<LongPointData> getLongGaugeData()
```
    Returns the long GaugeData if type is MetricDataType.LONG_GAUGE, otherwise a default empty data.
  - getDoubleSumData
```
default SumData<DoublePointData> getDoubleSumData()
```
    Returns the double SumData if type is MetricDataType.DOUBLE_SUM, otherwise a default empty data.
  - getLongSumData
```
default SumData<LongPointData> getLongSumData()
```
    Returns the long SumData if type is MetricDataType.LONG_SUM, otherwise a default empty data.
  - getSummaryData
```
default SummaryData getSummaryData()
```
    Returns the SummaryData if type is MetricDataType.SUMMARY, otherwise a default empty data.
  - getHistogramData
```
default HistogramData getHistogramData()
```
    Returns the HistogramData if type is MetricDataType.HISTOGRAM, otherwise a default empty data.
  - getExponentialHistogramData
```
default ExponentialHistogramData getExponentialHistogramData()
```
    Returns the ExponentialHistogramData if type is MetricDataType.EXPONENTIAL_HISTOGRAM, otherwise a default empty data.
