Class OpenTracingHelper.AgentTracer

java.lang.Object

com.datadoghq.agent.OpenTracingHelper.AgentTracer

All Implemented Interfaces:

io.opentracing.ActiveSpanSource, io.opentracing.Tracer

Enclosing class:

OpenTracingHelper

public static class OpenTracingHelper.AgentTracer
extends Object
implements io.opentracing.Tracer

Proxy tracer used for one purpose - to enable the rules to define a ChildOf relationship without being concerned whether the supplied Span is null. If the spec (and Tracer implementations) are updated to indicate a null should be ignored, then this proxy can be removed.
