 * 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.
