Class DateTimeSyntax is 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's Date value by calling getValue(). A date-time attribute's Date value is established when it is constructed (see DateTimeSyntax(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.Calendar object to construct a java.util.Date object, then use the java.util.Date object 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 a java.util.Calendar object and set it to the java.util.Date from the date-time attribute. Class DateTimeSyntax stores its value in the form of a java.util.Date rather than a java.util.Calendar because it typically takes less memory to store and less time to compare a java.util.Date than a java.util.Calendar.

Modifier and Type	Method	Description
protected Object	clone()	Answers a new instance of the same class as the receiver, whose slots have been filled in with the values in the slots of the receiver.
protected void	finalize()	Deprecated, for removal: This API element is subject to removal in a future version. May cause performance issues, deadlocks and hangs.
final Class<? extends Object>	getClass()	Answers the unique instance of java.lang.Class which represents the class of the receiver.
final void	notify()	Causes one thread which is waiting on the receiver to be made ready to run.
final void	notifyAll()	Causes all threads which are waiting on the receiver to be made ready to run.
final void	wait()	Causes the thread which sent this message to be made not ready to run pending some change in the receiver (as indicated by notify or notifyAll).
final void	wait(long time)	Causes the thread which sent this message to be made not ready to run either pending some change in the receiver (as indicated by notify or notifyAll) or the expiration of the timeout.
final void	wait(long time, int frac)	Causes the thread which sent this message to be made not ready to run either pending some change in the receiver (as indicated by notify or notifyAll) or the expiration of the timeout.

Constructor Details

DateTimeSyntax

protected DateTimeSyntax(Date value)

Construct a new date-time attribute with the given java.util.Date value.

Parameters:

value - java.util.Date value

Throws:

NullPointerException - if value is null

Method Details

getValue

public Date getValue()

Returns this date-time attribute's java.util.Date value.

Returns:

the Date

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:

1. object is not null.
2. object is an instance of class DateTimeSyntax.
3. This date-time attribute's java.util.Date value and object's java.util.Date value are equal.

Overrides:

equals in class Object

Parameters:

object - Object to compare to

Returns:

true if object is equivalent to this date-time attribute, false otherwise

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's java.util.Date value.

Overrides:

hashCode in class Object

Returns:

the receiver's hash.

See Also:

• Object.equals(Object)

toString

public String toString()

Returns a string value corresponding to this date-time attribute. The string value is just this attribute's java.util.Date value converted to a string.

Overrides:

toString in class Object

Returns:

String a printable representation for the receiver.
