Class TraceWrap

java.lang.Object

org.apache.accumulo.core.trace.wrappers.TraceWrap

public class TraceWrap
extends Object

To move trace data from client to server, the RPC call must be annotated to take a TInfo object as its first argument. The user can simply pass null, so long as they wrap their Client and Service objects with these functions.

 Trace.on("remoteMethod");
 Iface c = new Client();
 c = TraceWrap.client(c);
 c.remoteMethod(null, arg2, arg3);
 Trace.off();
 

The wrapper will see the annotated method and send or re-establish the trace information. Note that the result of these calls is a Proxy object that conforms to the basic interfaces, but is not your concrete instance.
