      boolean isStartRequired()
      Returns true if this SpanProcessor requires start events.
      Returns:
      true if this SpanProcessor requires start events.

    • onEnd

      void onEnd(ReadableSpan span)
      Called when a Span is ended, if the Span.isRecording() returns true.

      This method is called synchronously on the execution thread, should not throw or block the execution thread.

      Parameters:
      span - the Span that just ended.

    • isEndRequired

      boolean isEndRequired()
      Returns true if this SpanProcessor requires end events.
      Returns:
      true if this SpanProcessor requires end events.

    • shutdown
