stack commented on HTRACE-275:
------------------------------
If user calls wrap or getTracerPool, that is ok against NullTracer?
A subclass is returning an instance of superclass?
177 public static Tracer getNullTracer() {
178 return NullTracer.INSTANCE;
179 }
Otherwise looks good.
> Add NullTracer which never creates a trace span

> [~iwasakims] suggested adding a {{NullTracer}} which never creates a trace
> span. This would be more convenient than checking tracer objects against
> null in some cases.
