Class AbstractDateTime

java.lang.Object

org.goda.time.base.AbstractInstant

org.goda.time.base.AbstractDateTime

All Implemented Interfaces:

Comparable, ReadableDateTime, ReadableInstant

Direct Known Subclasses:

BaseDateTime

public abstract class AbstractDateTime
extends AbstractInstant
implements ReadableDateTime

AbstractDateTime provides the common behaviour for datetime classes.

This class should generally not be used directly by API users. The ReadableDateTime interface should be used when different kinds of date/time objects are to be referenced.

Whenever you want to implement ReadableDateTime you should extend this class.

AbstractDateTime subclasses may be mutable and not thread-safe.

Since:

1.0
