Class DefaultBackoffPolicy

java.lang.Object
org.multiverse.api.DefaultBackoffPolicy
All Implemented Interfaces:
BackoffPolicy
public final class DefaultBackoffPolicy extends Object implements BackoffPolicy
A BackoffPolicy that does an 'exponential' backoff. So each next attempt, the calculated delay is increased and randomized (so the next value can be smaller than the previous, but overall they will increase).

  • Constructor Details

    • DefaultBackoffPolicy

      public DefaultBackoffPolicy()
      Creates an ExponentialBackoffPolicy with 100 nanoseconds as minimal delay and 100 milliseconds as maximum delay.

    • DefaultBackoffPolicy

      public DefaultBackoffPolicy(long minDelayNs)
      Creates an ExponentialBackoffPolicy with given maximum delay.
      Parameters:
      minDelayNs - the minimum delay in nanoseconds to wait. If a negative or zero value provided, it will be interpreted that no external minimal value is needed.
      Throws:
      NullPointerException - if unit is null.
