spans - the collection of sampled Spans to be exported.

Returns:

the result of the export, which is often an asynchronous operation.

flush

public CompletableResultCode flush()

Flushes the data of all registered SpanExporters.

Specified by:

flush in interface SpanExporter

Returns:

the result of the operation

shutdown

public CompletableResultCode shutdown()

Description copied from interface: SpanExporter

Called when SdkTracerProvider.shutdown() is called, if this SpanExporter is registered to a SdkTracerProvider object.

Specified by:
