public abstract class DateTimeSyntax extends Object implements Serializable, Cloneable
ClassDateTimeSyntaxis an abstract base class providing the common implementation of all attributes whose value is a date and time.Under the hood, a date-time attribute is stored as a value of class
java.util.Date. You can get a date-time attribute'sDatevalue by callinggetValue(). A date-time attribute'sDatevalue is established when it is constructed (seeDateTimeSyntax(Date)). Once constructed, a date-time attribute's value is immutable.To construct a date-time attribute from separate values of the year, month, day, hour, minute, and so on, use a
java.util.Calendarobject to construct ajava.util.Dateobject, then use thejava.util.Dateobject to construct the date-time attribute. To convert a date-time attribute to separate values of the year, month, day, hour, minute, and so on, create ajava.util.Calendarobject and set it to thejava.util.Datefrom the date-time attribute. ClassDateTimeSyntaxstores its value in the form of ajava.util.Daterather than ajava.util.Calendarbecause it typically takes less memory to store and less time to compare ajava.util.Datethan ajava.util.Calendar.- See Also:

equals
public boolean equals(Object object)
Returns whether this date-time attribute is equivalent to the passed in object. To be equivalent, all of the following conditions must be true:objectis notnull.objectis an instance of classDateTimeSyntax.- This date-time attribute's
java.util.Datevalue andobject'sjava.util.Datevalue are equal.
- Overrides:
equalsin classObject- Parameters:

trueifobjectis equivalent to this date-time attribute,falseotherwise- See Also:
Object.hashCode()

hashCode
public int hashCode()
Returns a hash code value for this date-time attribute. The hashcode is that of this attribute'sjava.util.Datevalue.- Overrides:
hashCodein classObject- Returns:
- the receiver's hash.
