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
