Detailed Description

The Again class provides utility methods for retrying tasks with specified retry mechanisms, including simple retries with delays and retries with exponential backoff.

It retrieves configuration values such as retry times, retry delay, and retry activation from the Config instance. If retrying is not enabled in the configuration, tasks are executed without retries.

The class supports retrying tasks up to a maximum number of attempts with a specified delay between each attempt. It also supports exponential backoff, where the delay increases after each failure.

Member Function Documentation

delay()

static long io.github.kdesp73.databridge.helpers.Again.delay ( )

static

Gets the delay between retries from the configuration or uses the default value.

Returns

The delay between retries in milliseconds.

retries()

static int io.github.kdesp73.databridge.helpers.Again.retries ( )

static

Gets the maximum number of retry attempts from the configuration or uses the default value.

Returns

The maximum number of retry attempts.

retryWithDelay()

static< T > T io.github.kdesp73.databridge.helpers.Again.retryWithDelay ( RetryableTask< T > task, int maxRetries, long delay ) throws SQLException

static

Retries a task a specified number of times with a fixed delay between retries.

If retries are not enabled in the configuration, the task is executed without retries.

Parameters

task	The task to retry.
maxRetries	The maximum number of retry attempts.
delay	The delay between retry attempts in milliseconds.
<T>	The return type of the task.

Returns

The result of the task, or null if the task failed after the maximum retries.

Exceptions

SQLException

If an error occurs during task execution.

retryWithExponentialBackoff()

static< T > T io.github.kdesp73.databridge.helpers.Again.retryWithExponentialBackoff ( RetryableTask< T > task, int maxRetries, long initialDelay ) throws SQLException

static

Retries a task a specified number of times with exponential backoff between retries.

Exponential backoff doubles the delay between each retry attempt.

If retries are not enabled in the configuration, the task is executed without retries.

Parameters

task	The task to retry.
maxRetries	The maximum number of retry attempts.
initialDelay	The initial delay between retries in milliseconds.
<T>	The return type of the task.

Returns

The result of the task, or null if the task failed after the maximum retries.

Exceptions

SQLException

If an error occurs during task execution.
