Interface RequestCallback

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface RequestCallback

This functional interface may be used to handle request delivery instead of EReplier.request(EReplyFeed.ERequest) by passing a RequestCallback instance to EReplyFeed.requestCallback(RequestCallback). This allows a tighter coupling between a feed and the code for processing the feed's requests.

Note: This must be done after opening a EReplyFeed and before advertising.

Method Detail

call

void call(EReplyFeed.ERequest request)

An incoming request. The replier may send a reply either from within this method call or asynchronously after returning from this method. If the reply is sent asynchronously, then the replier must store request for later use. Replies are sent using ERequest and not EReplyFeed.

The request message is stored in request and can be retrieved by calling EReplyFeed.ERequest.request().

The request matches the replier's open and advertised feed. The associated EReplyFeed may be retrieved by calling EReplyFeed.ERequest.replier().

Parameters:

request - post replies to msg to this request.
