Class ExponentialTimeBackoff

java.lang.Object

cz.xtf.core.waiting.failfast.ExponentialTimeBackoff

public class ExponentialTimeBackoff
extends Object

Class provide support for exponential time backoff. This is convenient if you need to check some event periodically. The class provides next method that implements wait (blocking or non-blocking - returns true/false whether code can proceed).

Class wait time grow exponentially up to maxBackoffMillis time: 1sec, 2 sec, 4 sec, 8 sec,...,maxBackoffMillis.

Method Detail

builder

public static ExponentialTimeBackoff.Builder builder()

next

public boolean next()

Exponential backoff wait. If wait is blocking, Thread.sleep(long) is called and true is always returned. If wait is non-blocking, the method returns true if logic can proceed (enough time has elapsed)

Returns:

true if logic can proceed
