Interface RetryStrategy

All Superinterfaces:
Serializable
public interface RetryStrategy extends Serializable
Description of a strategy to take when an action fails, like when connecting to a server. An example strategy for this scenario can be: "attempt to reconnect 3 times, wait 5 seconds between each attempt, if all of them fail, give up".

The lifecycle of a retry strategy begins whenever an action fails and ends in one of two ways: either a retry of the action is successful (for example reconnection attempt to a server succeeds) or the strategy gives up (for example it did a specified maximum number of retries, all of them failed).

  • Method Details

    • getMaxAttempts

      int getMaxAttempts()
      Maximum number of retry attempt that should be made before giving up.

      A value of 0 should be interpreted as "never retry". Action is performed once.

      A negative value is interpreted as "retry indefinitely, until success".

    • getIntervalFunction

      IntervalFunction getIntervalFunction()
      Function specifying how much time to wait before each retry attempt. Can specify a constant wait time, exponential backoff or any other, arbitrarily complex wait strategy.
