Methods in com.linecorp.armeria.client.retry that return Backoff

Modifier and Type	Method and Description
static Backoff	Backoff.exponential(long initialDelayMillis, long maxDelayMillis) Returns a Backoff that waits an exponentially-increasing amount of time between attempts.
static Backoff	Backoff.exponential(long initialDelayMillis, long maxDelayMillis, double multiplier) Returns a Backoff that waits an exponentially-increasing amount of time between attempts.
static Backoff	Backoff.fibonacci(long initialDelayMillis, long maxDelayMillis) Returns a Backoff for which the backoff delay increases in line with the Fibonacci sequence f(n) = f(n-1) + f(n-2) where f(0) = f(1) = initialDelayMillis.
static Backoff	Backoff.fixed(long delayMillis) Returns a Backoff that waits a fixed delay between attempts.
static Backoff	Backoff.of(String specification) Creates a new Backoff that computes backoff delay using one of exponential(long, long, double), fibonacci(long, long), fixed(long) and random(long, long) chaining with withJitter(double, double) and withMaxAttempts(int) from the specification string that conforms to the following format: exponential=[initialDelayMillis:maxDelayMillis:multiplier] is for exponential(long, long, double) (multiplier will be 2.0 if it's omitted) fibonacci=[initialDelayMillis:maxDelayMillis] is for fibonacci(long, long) fixed=[delayMillis] is for fixed(long) random=[minDelayMillis:maxDelayMillis] is for random(long, long) jitter=[minJitterRate:maxJitterRate] is for withJitter(double, double) (if only one jitter value is specified, it will be used for withJitter(double) maxAttempts=[maxAttempts] is for withMaxAttempts(int) The order of options does not matter, and the specification needs at least one option.
static Backoff	Backoff.ofDefault() Returns the default Backoff.
static Backoff	Backoff.random(long minDelayMillis, long maxDelayMillis) Returns a Backoff that computes backoff delay which is a random value between minDelayMillis and maxDelayMillis chosen by ThreadLocalRandom.
static Backoff	Backoff.random(long minDelayMillis, long maxDelayMillis, Supplier<Random> randomSupplier) Returns a Backoff that computes backoff delay which is a random value between minDelayMillis and maxDelayMillis.
default Backoff	Backoff.withJitter(double jitterRate) Returns a Backoff that adds a random jitter value to the original delay using full jitter strategy.
default Backoff	Backoff.withJitter(double minJitterRate, double maxJitterRate) Returns a Backoff that adds a random jitter value to the original delay using full jitter strategy.
default Backoff	Backoff.withJitter(double minJitterRate, double maxJitterRate, Supplier<Random> randomSupplier) Returns a Backoff that adds a random jitter value to the original delay using full jitter strategy.
default Backoff	Backoff.withMaxAttempts(int maxAttempts) Returns a Backoff which limits the number of attempts up to the specified value.
static Backoff	Backoff.withoutDelay() Returns a Backoff that will never wait between attempts.
