Method Details

build

public Retry.ExponentialRetryPolicy build()

Description copied from interface: Builder

Build the instance from this builder.

Specified by:

build in interface Builder<Retry.ExponentialRetryPolicy.Builder,Retry.ExponentialRetryPolicy>

Returns:

instance of the built type

calls

public Retry.ExponentialRetryPolicy.Builder calls(int calls)

Total number of calls (first + retries).

Parameters:

calls - how many times to call the method

Returns:

updated builder instance

initialDelay

public Retry.ExponentialRetryPolicy.Builder initialDelay(Duration initialDelay)

Initial Delay.

Parameters:

initialDelay - Duration

Returns:

updated builder instance

maxDelay

public Retry.ExponentialRetryPolicy.Builder maxDelay(Duration maxDelay)

Max Delay in Milliseconds.

Parameters:

maxDelay - long

Returns:

updated builder instance

factor

public Retry.ExponentialRetryPolicy.Builder factor(int factor)

Multiplication factor.

Parameters:

factor - multiplication factor

Returns:

updated builder instance

jitter

public Retry.ExponentialRetryPolicy.Builder jitter(long jitter)

Random part of the delay. A number between [-jitter,+jitter] is applied to delay each time delay is calculated.

Parameters:

jitter - jitter duration

Returns:

updated builder instance

config

public Retry.ExponentialRetryPolicy.Builder config(Config config)

Load all properties for this Retry Policy from configuration.

Configuration

key	default value	description
calls	10	Number of calls
initial-delay	2	Initial delay
max-delay	3 minutes	Maximum delay
factor	2	Multiplication factor
jitter	50 milliseconds	A number between [-jitter,+jitter] applied to delay

Parameters:

config - the config node to use

Returns:

updated builder instance
