Interface Retry.RetryPolicy

All Known Implementing Classes:

Retry.DelayingRetryPolicy, Retry.ExponentialRetryPolicy, Retry.FibonacciRetryPolicy, Retry.JitterRetryPolicy

Enclosing interface:

Retry

public static interface Retry.RetryPolicy

Retry policy to handle delays between retries. The implementation must not save state, as a single instance will be used by multiple threads and executions in parallel.

Method Summary

Modifier and Type	Method	Description
Optional<Long>	nextDelayMillis(long firstCallMillis, long lastDelay, int call)	Return next delay in milliseconds, or an empty optional to finish retries.

Method Detail

nextDelayMillis

Optional<Long> nextDelayMillis(long firstCallMillis,
                               long lastDelay,
                               int call)

Return next delay in milliseconds, or an empty optional to finish retries.

Parameters:

firstCallMillis - milliseconds recorded before the first call using System.currentTimeMillis()

lastDelay - last delay that was used (0 for the first failed call)

call - call index (0 for the first failed call)

Returns:

how long to wait before trying again, or empty to notify this is the end of retries
