DEFAULT_SMOOTHING_FACTOR

public static final double DEFAULT_SMOOTHING_FACTOR

Deprecated.

The default smoothing factor. See Also:Constant Field Values

Constructor Detail

- 

ExponentialWeightedAverageStatistic

public ExponentialWeightedAverageStatistic()

Deprecated.

Creates an instance with DEFAULT_SMOOTHING_FACTOR.

- 

ExponentialWeightedAverageStatistic

public ExponentialWeightedAverageStatistic​(double smoothingFactor)

Deprecated.

Creates an instance. Parameters:smoothingFactor - The exponential smoothing factor.

Method Detail

- 

addSample

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 BandwidthStatisticParameters: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:reset in interface BandwidthStatistic
