Jetty 12.0.6 · org.eclipse.jetty.client.Destination · APIdia, the JavaDoc alternative

A Destination represents the receiver of HTTP requests, and it is identified by an Origin.

Destination holds a pool of Connections, but allows to create unpooled connections if the application wants full control over connection management via newConnection(Promise).

Destinations may be obtained via HttpClient#resolveDestination(Request).

Method Summary

Modifier and Type	Method and Description
public ConnectionPool	getConnectionPool() Returns: the connection pool associated with this destination
public HttpClient	getHttpClient() Returns: the `HttpClient` that manages this destination
public Origin	getOrigin() Returns: the origin of this destination
public ProxyConfiguration.Proxy	getProxy() Returns: the proxy associated with this destination, or `null` if there is no proxy
public boolean	isSecure() Returns: whether the communication with the destination is secure
public void	newConnection(Promise<Connection> the promise of a new, unpooled, `Connection` promise) Creates asynchronously a new, unpooled, `Connection` that will be returned at a later time through the given `Promise`.
public default CompletableFuture<Connection>	Returns: a `CompletableFuture` for a new, unpooled, `Connection` newConnection() Creates asynchronously a new, unpooled, `Connection` that will be returned at a later time through the given `Promise`.
public void	send(Request the request to send to this destination request, Response.CompleteListener the listener that receives response events listener) Sends the given request to this destination.

newConnection back to summary

newConnection	back to summary
public void newConnection(Promise<Connection> promise) Creates asynchronously a new, unpooled, `Connection` that will be returned at a later time through the given `Promise`. Use `FuturePromise` to wait for the connection: `Destination destination = ...; FuturePromise<Connection> futureConnection = new FuturePromise<>(); destination.newConnection(futureConnection); Connection connection = futureConnection.get(5, TimeUnit.SECONDS);` Parameters promise:Promise<Connection> the promise of a new, unpooled, `Connection`

public void newConnection(Promise<Connection> promise)

Creates asynchronously a new, unpooled, Connection that will be returned at a later time through the given Promise.

Use FuturePromise to wait for the connection:

Destination destination = ...;
FuturePromise<Connection> futureConnection = new FuturePromise<>();
destination.newConnection(futureConnection);
Connection connection = futureConnection.get(5, TimeUnit.SECONDS);

Parameters

promise:Promise<Connection>: the promise of a new, unpooled, Connection

newConnection	back to summary
public default CompletableFuture<Connection> newConnection() Creates asynchronously a new, unpooled, `Connection` that will be returned at a later time through the given `Promise`. Returns:CompletableFuture<Connection> a `CompletableFuture` for a new, unpooled, `Connection`

public default CompletableFuture<Connection> newConnection()

Creates asynchronously a new, unpooled, Connection that will be returned at a later time through the given Promise.

Returns:CompletableFuture<Connection>: a CompletableFuture for a new, unpooled, Connection

send back to summary

send	back to summary
public void send(Request request, Response.CompleteListener listener) Sends the given request to this destination. You can use this method to send the request to a specific destination that may be different from the request authority. For example when `HttpClient` is used in a proxy, it may receive a request with authority `yourserver.com` but the proxy logic may want to forward the request to a specific backend server, say `backend01`, therefore: `// Resolve the backend destination. Origin backendOrigin = new Origin(backendScheme, "backend01", backendPort); Destination backendDestination = httpClient.resolveDestination(backendOrigin); // Create a request with the original authority. Request request = httpClient.newRequest("https://yourserver.com/path"); // Send the request to the specific backend. backendDestination.send(request, result -> { ... });` Parameters request:Request the request to send to this destination listener:Response.CompleteListener the listener that receives response events

public void send(Request request, Response.CompleteListener listener)

Sends the given request to this destination.

You can use this method to send the request to a specific destination that may be different from the request authority.

For example when HttpClient is used in a proxy, it may receive a request with authority yourserver.com but the proxy logic may want to forward the request to a specific backend server, say backend01, therefore:

// Resolve the backend destination.
Origin backendOrigin = new Origin(backendScheme, "backend01", backendPort);
Destination backendDestination = httpClient.resolveDestination(backendOrigin);

// Create a request with the original authority.
Request request = httpClient.newRequest("https://yourserver.com/path");

// Send the request to the specific backend.
backendDestination.send(request, result -> { ... });

Parameters

request:Request: the request to send to this destination
listener:Response.CompleteListener: the listener that receives response events

public Interface Destination
