successFunction

@UnstableApi
public AbstractClientOptionsBuilder successFunction(SuccessFunction successFunction)

endpointRemapper

public AbstractClientOptionsBuilder endpointRemapper(Function<? super Endpoint,? extends EndpointGroup> endpointRemapper)

Sets a Function that remaps an Endpoint into an EndpointGroup. This ClientOption is useful when you need to override a single target host into a group of hosts to enable client-side load-balancing, e.g.

 MyService.Iface client =
     Clients.newClient("tbinary+http://example.com/api",
                       MyService.Iface.class);

 EndpointGroup myGroup = EndpointGroup.of(Endpoint.of("node-1.example.com")),
                                          Endpoint.of("node-2.example.com")));

 MyService.Iface derivedClient =
     Clients.newDerivedClient(client, options -> {
         return options.toBuilder()
                       .endpointRemapper(endpoint -> {
                           if (endpoint.host().equals("example.com")) {
                               return myGroup;
                           } else {
                               return endpoint;
                           }
                       })
                       .build();
     });

 // This request goes to 'node-1.example.com' or 'node-2.example.com'.
 derivedClient.call();
 

Note that the remapping does not occur recursively but only once.

addHeader

public AbstractClientOptionsBuilder addHeader(CharSequence name,
 Object value)

Adds the default HTTP header for an HttpRequest that will be sent by this Client.

Note that the values of the default HTTP headers could be overridden if the same HttpHeaderNames are defined in the HttpRequest.headers() or ClientRequestContext.additionalRequestHeaders().

addHeaders

public AbstractClientOptionsBuilder addHeaders(Iterable<? extends Map.Entry<? extends CharSequence,?>> headers)

Adds the default HTTP headers for an HttpRequest that will be sent by this Client.

Note that the values of the default HTTP headers could be overridden if the same HttpHeaderNames are defined in the HttpRequest.headers() or ClientRequestContext.additionalRequestHeaders().

setHeader

public AbstractClientOptionsBuilder setHeader(CharSequence name,
 Object value)

Sets the RedirectConfig to enable automatic redirection.

contextCustomizer

@UnstableApi
public AbstractClientOptionsBuilder contextCustomizer(Consumer<? super ClientRequestContext> contextCustomizer)

Adds the specified ClientRequestContext customizer function so that it customizes the context in the thread that initiated the client call. The given customizer function is evaluated before the customizer function specified by Clients.withContextCustomizer(Consumer).

 static final ThreadLocal<String> USER_ID = new ThreadLocal<>();
 static final AttributeKey<String> USER_ID_ATTR = AttributeKey.valueOf("USER_ID");
 ...
 MyClientStub client =
     Clients.builder(...)
            .contextCustomizer(ctx -> {
                // This customizer will be invoked from the thread that initiates a client call.
                ctx.setAttr(USER_ID_ATTR, USER_ID.get());
            })
            .build(MyClientStub.class);

 // Good:
 // The context data is set by the thread that initiates the client call.
 USER_ID.set("user1");
 try {
     client.executeSomething1(..);
     ...
     client.executeSomethingN(..);
 } finally {
     // Should clean up the thread local storage.
     USER_ID.remove();
 }

 // Bad:
 USER_ID.set("user1");
 executor.execute(() -> {
     // The variable in USER_ID won't be propagated to the context.
     // The variable is not valid at the moment client.executeSomething1() is called.
      client.executeSomething1(..);
 });
 

Note that certain properties of ClientRequestContext, such as:

• ClientRequestContext.endpoint()
• RequestContext.localAddress()
• RequestContext.remoteAddress()

may be null while the customizer function runs, because the target host of the Request is not determined yet.

• Clients.withContextCustomizer(Consumer)

buildOptions

protected final ClientOptions buildOptions()

Builds ClientOptions with the given options and the default options.

buildOptions

protected final ClientOptions buildOptions(@Nullable
 @Nullable ClientOptions baseOptions)

Builds ClientOptions with the specified baseOptions and the options which were set to this builder.
