public void addSample(long bytes,
                      long durationUs)
```
    Deprecated.
    
    Description copied from interface: BandwidthStatistic
    
    Adds a transfer sample to the statistic.
    
    Specified by:
    
    addSample in interface BandwidthStatistic
    
    Parameters:
    
    bytes - The number of bytes transferred.
    
    durationUs - The duration of the transfer, in microseconds.
  - getBandwidthEstimate
```
public long getBandwidthEstimate()
```
    Deprecated.
    
    Description copied from interface: BandwidthStatistic
    
    Returns the bandwidth estimate in bits per second, or BandwidthEstimator.ESTIMATE_NOT_AVAILABLE if there is no estimate available yet.
    
    Specified by:
    
    getBandwidthEstimate in interface BandwidthStatistic
  - reset
```
public void reset()
```
    Deprecated.
    
    Description copied from interface: BandwidthStatistic
    
    Resets the statistic. The statistic should drop all samples and reset to its initial state, similar to right after construction.
    
    Specified by:
