Interface ResponseInterceptor

All Known Implementing Classes:

RedirectionInterceptor

public interface ResponseInterceptor

ResponseInterceptors may be configured for purposes such as verifying or modifying headers of response, verifying the business status of decoded object, or processing responses to unsuccessful requests. Once the interceptors are applied, intercept(InvocationContext, Chain) is called, then the response is decoded.

Nested Class Summary

Nested Classes

Modifier and Type	Interface and Description
static interface	ResponseInterceptor.Chain Contract for delegation to the rest of the chain.

Method Summary

Modifier and Type	Method and Description
default ResponseInterceptor	andThen(ResponseInterceptor nextInterceptor) Return a new ResponseInterceptor that invokes the current interceptor first and then the one that is passed in.
default ResponseInterceptor.Chain	apply(ResponseInterceptor.Chain chain) Apply this interceptor to the given Chain resulting in an intercepted chain.
Object	intercept(InvocationContext invocationContext, ResponseInterceptor.Chain chain) Called by ResponseHandler after refreshing the response and wrapped around the whole decode process, must either manually invoke ResponseInterceptor.Chain.next(InvocationContext) or manually create a new response object

Method Detail

intercept

Object intercept(InvocationContext invocationContext,
                 ResponseInterceptor.Chain chain)
          throws Exception

Called by ResponseHandler after refreshing the response and wrapped around the whole decode process, must either manually invoke ResponseInterceptor.Chain.next(InvocationContext) or manually create a new response object

Parameters:

invocationContext - information surrounding the response being decoded

Returns:

decoded response

Throws:

Exception

andThen

default ResponseInterceptor andThen(ResponseInterceptor nextInterceptor)

Return a new ResponseInterceptor that invokes the current interceptor first and then the one that is passed in.

Parameters:

nextInterceptor - the interceptor to delegate to after the current

Returns:

a new interceptor that chains the two

apply

default ResponseInterceptor.Chain apply(ResponseInterceptor.Chain chain)

Apply this interceptor to the given Chain resulting in an intercepted chain.

Parameters:

chain - the chain to add interception around

Returns:

a new chain instance
