Method Summary

Modifier and Type	Method	Description
static ExportComponentImpl	createWithInProcessStores(EventQueue eventQueue)	Returns a new ExportComponentImpl that has valid instances for RunningSpanStore and SampledSpanStore.
static ExportComponentImpl	createWithoutInProcessStores(EventQueue eventQueue)	Returns a new ExportComponentImpl that has null instances for RunningSpanStore and SampledSpanStore.
InProcessRunningSpanStore	getRunningSpanStore()	Returns the RunningSpanStore that can be used to get useful debugging information about all the current active spans.
SampledSpanStoreImpl	getSampledSpanStore()	Returns the SampledSpanStore that can be used to get useful debugging information, such as latency based sampled spans, error based sampled spans.
SpanExporterImpl	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()).
void	shutdown()	Will shutdown this ExportComponent after flushing any pending spans.
