ExponentialBackoff

class ~~ExponentialBackoff~~(baseTimeMillis: Long = DEFAULT_BASE_TIME_MILLIS, multiplier: Float = DEFAULT_MULTIPLIER, minimumDelayMillis: Long = DEFAULT_MINIMUM_DELAY, maximumDelayMillis: Long = DEFAULT_MAXIMUM_DELAY) : DelayStrategy

Deprecated

DelayStrategy with an exponentially increasing delay, calculated with getExponentialBackoffMillis.

minimumDelayMillis indicates the capped minimum delay (in milliseconds). maximumDelayMillis indicates the capped maximum delay (in milliseconds).

Delay is calculated using the following formula:

delay = base * multiplier ^ iteration

For example (using base = 100 and multiplier = 2):

iteration	delay
0	100
1	200
2	400
3	800
4	1600
...	...
