* Superclass for {@link MessageEvent} and {@link NetworkEvent} to resolve API backward
* compatibility issue.
*
* {@code SpanData.create} can't be overloaded with parameter types that differ only in the type
* of the TimedEvent, because the signatures are the same after generic type erasure. {@code
* BaseMessageEvent} allows the same method to accept both {@code TimedEvents} and
* {@code TimedEvents}.
*
* This class should only be extended by {@code NetworkEvent} and {@code MessageEvent}.
*
* @deprecated This class is for internal use only.
* @since 0.12
