----------------------------
Summary: API improvements
Key: HTRACE-261
URL: https://issues.apache.org/jira/browse/HTRACE-261
Project: HTrace
Issue Type: Improvement
Affects Versions: 5.0.0
Reporter: stack
Umbrella issue to keep track of API improvments to do for htrace 5.0
detach and reattach should return this. Ditto on the annotations.
curThreadTracer should be currentThreadTracer or getCurrentThreadTracer
Have to do too much checking for null when use the 4.0 API; e.g. checking if
tracer is null.
In 3.x, there was an isTracing but now you have to get Span from Scope and if
it is null, then you know you are not tracing... not as clean as isTracing.
TraceScope is meant as the Tracing Interface; it hides Spans. Its coverage is
not complete though. For example, to add a Parent, you have to get the Span
from the Scope and add the Parent there.
