Example 26 with Span

use of com.uber.jaeger.Span in project jaeger-client-java by jaegertracing.

the class ZipkinSenderTest method testAppend.

    // this allows us to test the boundary conditions of writing spans.

    sender.close();
    sender = newSender(messageMaxBytes);
    // add enough spans to be under buffer limit
