Interface ReadableDateTime

All Superinterfaces:

Comparable, ReadableInstant

All Known Subinterfaces:

ReadWritableDateTime

All Known Implementing Classes:

AbstractDateTime, BaseDateTime, DateMidnight, DateTime, MutableDateTime

public interface ReadableDateTime

extends ReadableInstant

Defines an instant in time that can be queried using datetime fields.

The implementation of this interface may be mutable or immutable. This interface only gives access to retrieve data, never to change it.

Methods in your application should be defined using ReadableDateTime as a parameter if the method only wants to read the datetime, and not perform any advanced manipulations.
