InterceptorFlowController (membrane-esb-core 3.4.0 API)

```
public class InterceptorFlowController
extends Object
```
Controls the flow of an exchange through a chain of interceptors. In the trivial setup, an exchange passes through two chains until it hits Outcome.RETURN: The main chain owned by the Transport (containing the RuleMatching, Dispatching, UserFeature and HttpClient-Interceptors) and the inner chain owned by the UserFeatureInterceptor (containing any interceptor configured in proxies.xml). The HTTPClientInterceptor, the last interceptor in the main chain, always returns Outcome.RETURN or Outcome.ABORT, never Outcome.CONTINUE. Any chain is followed using Interceptor.handleRequest(Exchange) until it hits Outcome.RETURN or Outcome.ABORT. As the chain is followed, every interceptor (except those with Flow#REQUEST) are added to the exchange's stack. When Outcome.RETURN is hit, the exchange's interceptor stack is unwound and Interceptor.handleResponse(Exchange) is called for every interceptor on it. When Outcome.ABORT is hit, handling is aborted: An AbortException is thrown and the stack is not unwound. (Note that this is subject to change: In some future implementation, the stack is to be unwound in this case and a new method handleAbort(Exchange) is to be called for every interceptor on it.)
