| * A date-time without a time-zone in an arbitrary chronology, intended |
| * for advanced globalization use cases. |
| * <p> |
| * <b>Most applications should declare method signatures, fields and variables |
| * as {@link LocalDateTime}, not this interface.</b> |
| * <p> |
| * A {@code ChronoLocalDateTime} is the abstract representation of a local date-time |
| * where the {@code Chronology chronology}, or calendar system, is pluggable. |
| * The date-time is defined in terms of fields expressed by {@link TemporalField}, |
| * where most common implementations are defined in {@link ChronoField}. |
| * The chronology defines how the calendar system operates and the meaning of |
| * the standard fields. |
| * |
| * <h2>When to use this interface</h2> |
| * The design of the API encourages the use of {@code LocalDateTime} rather than this |
| * interface, even in the case where the application needs to deal with multiple |
| * calendar systems. The rationale for this is explored in detail in {@link ChronoLocalDate}. |
| * <p> |
| * Ensure that the discussion in {@code ChronoLocalDate} has been read and understood |
| * before using this interface. |
| * |
| * @implSpec |
| * This interface must be implemented with care to ensure other classes operate correctly. |
| * All implementations that can be instantiated must be final, immutable and thread-safe. |
| * Subclasses should be Serializable wherever possible. |
| * |
| * @param <D> the concrete type for the date of this date-time |
