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.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 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.

Constructor Detail
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 - (unchecked exception) Thrown if theValue is null.
Method Detail
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:
- object is not null.
- object is an instance of class DateTimeSyntax.
- 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.

- Object.hashCode(), Hashtable
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:
- a hash code value for this object.
- See Also:
- Object.equals(java.lang.Object), Hashtable
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:
- a string representation of the object.
