Modifier and Type	Method and Description
`static double`	`computeAlpha(double targetWeight, long targetAgeInSeconds)` Compute the alpha decay factor such that the weight of an entry with age 'targetAgeInSeconds' is targetWeight'
`static double`	`fifteenMinutes()`
`static double`	`fiveMinutes()`
`static double`	`oneMinute()`
`static double`	`seconds(int seconds)`
`static double`	`weight(double alpha, long now, long landmark)` Compute the forward-decay multiplier (inverse of the decay factor)
