/**
* Obtains an instance of {@code LocalDateTime} from a temporal object.
* <p>
* This obtains a local date-time based on the specified temporal.
* A {@code TemporalAccessor} represents an arbitrary set of date and time information,
* which this factory converts to an instance of {@code LocalDateTime}.
* <p>
* The conversion extracts and combines the {@code LocalDate} and the
* {@code LocalTime} from the temporal object.
* Implementations are permitted to perform optimizations such as accessing
* those fields that are equivalent to the relevant objects.
* <p>
* This method matches the signature of the functional interface {@link TemporalQuery}
* allowing it to be used as a query via method reference, {@code LocalDateTime::from}.
*
* @param TemporalAccessor $temporal the temporal object to convert, not null
* @return LocalDateTime the local date-time, not null
* @throws DateTimeException if unable to convert to a {@code LocalDateTime}
