Method Summary

Methods
Modifier and Type	Method and Description
`<T,E extends Throwable> void`	`close(RetryContext context, RetryCallback<T,E> callback, Throwable throwable)` Called after the final attempt (successful or not).
`<T,E extends Throwable> void`	`onError(RetryContext context, RetryCallback<T,E> callback, Throwable throwable)` Called after every unsuccessful attempt at a retry.
`<T,E extends Throwable> boolean`	`open(RetryContext context, RetryCallback<T,E> callback)` Called before the first attempt in a retry.

- Method Detail
  - open
```
<T,E extends Throwable> boolean open(RetryContext context,
                                   RetryCallback<T,E> callback)
```
    Called before the first attempt in a retry. For instance, implementers can set up state that is needed by the policies in the RetryOperations. The whole retry can be vetoed by returning false from this method, in which case a TerminatedRetryException will be thrown.
    
    Parameters:
    context - the current RetryContext.
    callback - the current RetryCallback.
    
    Returns:
    true if the retry should proceed.
  - close
```
<T,E extends Throwable> void close(RetryContext context,
                                 RetryCallback<T,E> callback,
                                 Throwable throwable)
```
    Called after the final attempt (successful or not). Allow the interceptor to clean up any resource it is holding before control returns to the retry caller.
    
    Parameters:
    context - the current RetryContext.
    callback - the current RetryCallback.
    throwable - the last exception that was thrown by the callback.
  - onError
```
<T,E extends Throwable> void onError(RetryContext context,
                                   RetryCallback<T,E> callback,
                                   Throwable throwable)
```
    Called after every unsuccessful attempt at a retry.
    
    Parameters:
    context - the current RetryContext.
    callback - the current RetryCallback.
    throwable - the last exception that was thrown by the callback.
