Class HttpBackOffIOExceptionHandler (1.45.3)

public class HttpBackOffIOExceptionHandler implements HttpIOExceptionHandler

Beta
HttpIOExceptionHandler implementation with BackOff.

It is designed to work with only one HttpRequest at a time. As a result you MUST create a new instance of HttpBackOffIOExceptionHandler with a new instance of BackOff for each instance of HttpRequest.

Sample usage:

request.setIOExceptionHandler(new HttpBackOffIOExceptionHandler(new ExponentialBackOff());

Note: Implementation doesn't call BackOff#reset at all, since it expects a new BackOff instance.

Implementation is not thread-safe

handleIOException(HttpRequest request, boolean supportsRetry)

public boolean handleIOException(HttpRequest request, boolean supportsRetry)

Invoked when an IOException is thrown during an HTTP request.

There is a simple rule that one must follow: If you modify the request object or modify its execute interceptors in a way that should resolve the error, you must return true to issue a retry.

Handles the request with BackOff. That means that if back-off is required a call to Sleeper#sleep(long) will be made.

Parameters
Name	Description
`request`	`HttpRequest`
`supportsRetry`	`boolean`

Returns
Type	Description
`boolean`

Exceptions
Type	Description
`IOException`

setSleeper(Sleeper sleeper)

public HttpBackOffIOExceptionHandler setSleeper(Sleeper sleeper)

The default value is Sleeper#DEFAULT.

Overriding is only supported for the purpose of calling the super implementation and changing the return type, but nothing else.

Parameter
