use of com.twitter.zipkin.gen.Span in project zipkin by openzipkin.

the class TracedSession method update.

@Override
public void update(Host host, Statement statement, Exception e, long nanos) {
    if (!(statement instanceof NamedBoundStatement))
        return;
    Span span = cache.remove(statement);
    if (span == null) {

        }
        return;
    }
    Span previous = brave.clientSpanThreadBinder().getCurrentClientSpan();
    brave.clientSpanThreadBinder().setCurrentSpan(span);
    try {

            brave.clientTracer().submitBinaryAnnotation(Constants.ERROR, e.getMessage());
        }
    } finally {
        // TODO: on brave 4, set host to remote address
        brave.clientTracer().setClientReceived();
        brave.clientSpanThreadBinder().setCurrentSpan(previous);
    }
}
