Method Detail

addResponse

public final T addResponse(Address sender,
                           Response response)

Description copied from interface: ResponseCollector

Called when a response is received, or when a target node becomes unavailable.

When a target node leaves the cluster, this method is called with a CacheNotFoundResponse.

Should return a non-null result if the request should complete with that value, or null if it should wait for more responses. If the method throws an exception, the request will be completed with that exception. If the last response is received and addResponse() still returns null, ResponseCollector.finish() will also be called to obtain a result.

Thread safety: addResponse() will *not* be called concurrently from multiple threads, and the request will not be completed while addResponse() is running.

Specified by:

addResponse in interface ResponseCollector<T>

finish

public final T finish()

Description copied from interface: ResponseCollector

Called after ResponseCollector.addResponse(Address, Response) returns null for the last response.

If finish() finishes normally, the request will complete with its return value (even if null). If finish() throws an exception, the request will complete exceptionally with that exception, wrapped in a CompletionException (unless the exception is already a CompletionException).

Specified by:

finish in interface ResponseCollector<T>
