Measurement

All Known Implementing Classes:

AutoValue_ImmutableMeasurement, ImmutableMeasurement, MutableMeasurement
```
public interface Measurement
```
A long or double measurement recorded from ObservableLongMeasurement or ObservableDoubleMeasurement.
This class is internal and is hence not for public use. Its APIs are unstable and can change at any time.

- Method Detail
  - startEpochNanos
```
long startEpochNanos()
```
  - epochNanos
```
long epochNanos()
```
  - hasLongValue
```
boolean hasLongValue()
```
  - longValue
```
long longValue()
```
  - hasDoubleValue
```
boolean hasDoubleValue()
```
  - doubleValue
```
double doubleValue()
```
  - attributes
```
Attributes attributes()
```
  - withAttributes
```
Measurement withAttributes(Attributes attributes)
```
    Updates the attributes.
    
    Parameters:
    
    attributes - The attributes to update
    
    Returns:
    
    The updated object. For ImmutableMeasurement it will be a new object with the updated attributes and for MutableMeasurement it will return itself with the attributes updated
  - withStartEpochNanos
```
Measurement withStartEpochNanos(long startEpochNanos)
```
    Updates the startEpochNanos.
    
    Parameters:
    
    startEpochNanos - start epoch nanosecond
    
    Returns:
    
    The updated object. For ImmutableMeasurement it will be a new object with the updated startEpochNanos and for MutableMeasurement it will return itself with the startEpochNanos updated
