/** A poll message that is pending for a registrar. */
/**
* A poll message that is pending for a registrar.
*
* <p>Poll messages are not delivered until their {@link #eventTime} has passed. Poll messages can
* be speculatively enqueued for future delivery, and then modified or deleted before that date has
* passed. Unlike most other entities in Datastore, which are marked as deleted but otherwise
* retained for historical purposes, poll messages are truly deleted once they have been delivered
* and ACKed.
*
* <p>Poll messages are parented off of the {@link HistoryEntry} that resulted in their creation.
* This means that poll messages are contained in the Datastore entity group of the parent {@link
* EppResource} (which can be a domain, application, contact, or host). It is thus possible to
* perform a strongly consistent query to find all poll messages associated with a given EPP
* resource.
*
* <p>Poll messages are identified externally by registrars using the format defined in {@link
* PollMessageExternalKeyConverter}.
*
* @see "https://tools.ietf.org/html/rfc5730#section-2.9.2.3"
