- com.rabbitmq.client.RecoveryDelayHandler.ExponentialBackoffDelayHandler

All Implemented Interfaces:

RecoveryDelayHandler

Enclosing interface:

RecoveryDelayHandler
```
public static class RecoveryDelayHandler.ExponentialBackoffDelayHandler
extends Object
implements RecoveryDelayHandler
```
Backoff implementation of RecoveryDelayHandler that uses the Fibonacci sequence (by default) to increase the recovery delay time after each failed attempt. You can optionally use your own backoff sequence.

public long getDelay(int recoveryAttempts)
```
    Description copied from interface: RecoveryDelayHandler
    
    Get the time to sleep (in milliseconds) before attempting to reconnect and recover again. This method will be called with recoveryAttempts=0 before the first recovery attempt and then again after each failed recovery.
    
    Specified by:
    
    getDelay in interface RecoveryDelayHandler
    
    Parameters:
    
    recoveryAttempts - The number of recovery attempts so far.
    
    Returns:
    
    the delay in milliseconds
