TimeAverageMessageData

public TimeAverageMessageData()

TimeAverageMessageData

public TimeAverageMessageData(int maxSamples)

Initialize this TimeAverageData to 0 values.

Parameters:

maxSamples - The maximum number of samples with which to maintain the average.

TimeAverageMessageData

public TimeAverageMessageData(int maxSamples,
                              org.apache.pulsar.policies.data.loadbalancer.NamespaceBundleStats defaultStats)
