java.time.chrono.ChronoLocalDateTime

A date-time without a time-zone in an arbitrary chronology, intended for advanced globalization use cases.

Most applications should declare method signatures, fields and variables as {@link LocalDateTime}, not this interface.

A {@code ChronoLocalDateTime} is the abstract representation of a local date-timewhere 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.

When to use this interface

The design of the API encourages the use of {@code LocalDateTime} rather than thisinterface, 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}.

Ensure that the discussion in {@code ChronoLocalDate} has been read and understoodbefore 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 @since 1.8
