ome.formats.importer.util.ProportionalTimeEstimatorImpl

All Implemented Interfaces:

TimeEstimator

public class ProportionalTimeEstimatorImpl
extends Object
implements TimeEstimator

Class implementing the TimeEstimator interface. Uses the Exponential Moving Average equation to provide an estimate of the remaining upload time of binary data. A correction factor is used for minimal overestimation.
