- Field Detail
  - RETRIES_ATTEMPTED_CEILING
```
static final int RETRIES_ATTEMPTED_CEILING
```
    Max permitted retry times. To prevent exponentialDelay from overflow, there must be 2 ^ retriesAttempted <= 2 ^ 31 - 1, which means retriesAttempted <= 30, so that is the ceil for retriesAttempted.
- Method Detail
  - computeDelayBeforeNextRetry
```
Duration computeDelayBeforeNextRetry(RetryPolicyContext context)
```
    Compute the delay before the next retry request. This strategy is only consulted when there will be a next retry.
    
    Parameters:
    
    context - Context about the state of the last request and information about the number of requests made.
    
    Returns:
    
    Amount of time in milliseconds to wait before the next attempt. Must be non-negative (can be zero).
