      • disableDrainingRequestPayloadBody

        public final HttpServerBuilder disableDrainingRequestPayloadBody()
        Disables automatic consumption of request payload body when it is not consumed by the service.

        For persistent HTTP connections it is required to eventually consume the entire request payload to enable reading of the next request. This is required because requests are pipelined for HTTP/1.1, so if the previous request is not completely read, next request can not be read from the socket. For cases when there is a possibility that user may forget to consume request payload, ServiceTalk automatically consumes request payload body. This automatic consumption behavior may create some overhead and can be disabled using this method when it is guaranteed that all request paths consumes all request payloads eventually. An example of guaranteed consumption are non-streaming APIs.

        Returns:
        this.

      • allowDropRequestTrailers

        public abstract HttpServerBuilder allowDropRequestTrailers​(boolean allowDrop)
        Provide a hint if request trailers are allowed to be dropped. This hint maybe ignored if the transport can otherwise infer that the trailers should be preserved. For example, if the request headers contain Trailer then this hint maybe ignored.
        Parameters:
        allowDrop - true if request trailers are allowed to be dropped.
        Returns:
        this

      • appendConnectionAcceptorFilter

        public final HttpServerBuilder appendConnectionAcceptorFilter​(ConnectionAcceptorFactory factory)
        Appends the filter to the chain of filters used to decorate the ConnectionAcceptor used by this builder.

        The order of execution of these filters are in order of append. If 3 filters are added as follows: 

             builder.appendConnectionAcceptorFilter(filter1).appendConnectionAcceptorFilter(filter2).
     appendConnectionAcceptorFilter(filter3)
        accepting a connection by a filter wrapped by this filter chain, the order of invocation of these filters will be: 
             filter1 => filter2 => filter3
        Parameters:
        factory - ConnectionAcceptorFactory to append. Lifetime of this ConnectionAcceptorFactory is managed by this builder and the server started thereof.
        Returns:
        this

      • appendServiceFilter

        public final HttpServerBuilder appendServiceFilter​(java.util.function.Predicate<StreamingHttpRequest> predicate,
                                                   StreamingHttpServiceFilterFactory factory)
        Appends the filter to the chain of filters used to decorate the StreamingHttpService used by this builder, for every request that passes the provided Predicate.

        Note this method will be used to decorate the StreamingHttpService passed to listenStreaming(StreamingHttpService) before it is used by the server.

        The order of execution of these filters are in order of append. If 3 filters are added as follows: 

             builder.append(filter1).append(filter2).append(filter3)
        accepting a request by a service wrapped by this filter chain, the order of invocation of these filters will be: 
             filter1 => filter2 => filter3 => service
        Parameters:
        predicate - the Predicate to test if the filter must be applied.
        factory - StreamingHttpServiceFilterFactory to append.
        Returns:
        this
