Modifier and Type	Method	Description
abstract RunningSpanStore	getRunningSpanStore()	Returns the RunningSpanStore that can be used to get useful debugging information about all the current active spans.
abstract SampledSpanStore	getSampledSpanStore()	Returns the SampledSpanStore that can be used to get useful debugging information, such as latency based sampled spans, error based sampled spans.
abstract SpanExporter	getSpanExporter()	Returns the SpanExporter which can be used to register handlers to export all the spans that are part of a distributed sampled trace (see TraceOptions.isSampled()).
static ExportComponent	newNoopExportComponent()	Returns the no-op implementation of the ExportComponent.
