Interface TraceContext.Injector<C>

Enclosing class:

TraceContext

public static interface TraceContext.Injector<C>

Used to send the trace context downstream. For example, as http headers.

For example, to put the context on an HttpURLConnection, you can do this:

 // in your constructor
 injector = tracing.propagation().injector(URLConnection::setRequestProperty);

 // later in your code, reuse the function you created above to add trace headers
 HttpURLConnection connection = (HttpURLConnection) new URL("http://myserver").openConnection();
 injector.inject(span.context(), connection);
