How does the library handle spans?

[simplekjl]

General question,

I am currently creating spans to wrap traces for my different user flows but I want to know if the current implementation handle the spans internally or not

    override fun startTrace(traceName: String, initialAttributes: Attributes) {
        // Avoid duplicate spans for same logical name
        if (activeSpans.putIfAbsent(
                traceName,
                SpanHolder(Span.getInvalid(), Scope.noop())
            ) != null
        ) {
            logController.w(javaClass.simpleName) { "Trace '$traceName' already active. Ignoring start." }
            return
        }

        val span = getTracer(SCOPE_DEFAULT)
            .spanBuilder(traceName)
            .setSpanKind(SpanKind.INTERNAL)
            .setAllAttributes(initialAttributes)
            .startSpan()

        val scope = span.makeCurrent()
        activeSpans[traceName] = SpanHolder(span, scope)
        logController.d(javaClass.simpleName) { "Trace started: '$traceName', ID: ${span.spanContext.traceId}" }
    }

    override fun endTrace(traceName: String, finalAttributes: Attributes) {
        val holder = activeSpans.remove(traceName)
        if (holder == null) {
            logController.w(javaClass.simpleName) { "No active trace for '$traceName'. Ignoring end." }
            return
        }
        // Ensure scope is always closed
        try {
            holder.span.setAllAttributes(finalAttributes)
        } finally {
            try {
                holder.scope.close()
            } finally {
                holder.span.end()
            }
        }
        logController.d(javaClass.simpleName) { "Trace ended: '$traceName', ID: ${holder.span.spanContext.traceId}" }
    }

Above my current implementation assuming the library doesn't handle span history.

Is there a easier way achieve this?
