## javax.print.attribute
Class DateTimeSyntax

    java.lang.Object
      javax.print.attribute.DateTimeSyntax

All Implemented Interfaces:
  Serializable, Cloneable

Direct Known Subclasses:
  DateTimeAtCompleted, DateTimeAtCreation, DateTimeAtProcessing, JobHoldUntil

    public abstract class DateTimeSyntax

extends Object
implements Serializable, Cloneable

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`.

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:
  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()`, `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.
