All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`AggregationTemporality`	`getAggregationTemporality()`	Returns the `AggregationTemporality` of this metric,

`boolean`	`isMonotonic()`	Returns "true" if the sum is monotonic.

- Method Detail
  - isMonotonic
```
boolean isMonotonic()
```
    Returns "true" if the sum is monotonic.
    
    Returns:
    
    "true" if the sum is monotonic
  - getAggregationTemporality
```
AggregationTemporality getAggregationTemporality()
```
    Returns the AggregationTemporality of this metric,
    AggregationTemporality describes if the aggregator reports delta changes since last report time, or cumulative changes since a fixed start time.
    
    Returns:
    
    the AggregationTemporality of this metric
  - getPoints
```
Collection<T> getPoints()
```
    Returns the data PointDatas for this metric.
    
    Returns:
    
    the data PointDatas for this metric, or empty Collection if no points.
