- javax.print.attribute.DateTimeSyntax

All Implemented Interfaces:

Serializable, Cloneable

Direct Known Subclasses:

```
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 - if value 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
    
    See Also:
    
    Object.hashCode(), HashMap
  - 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), System.identityHashCode(java.lang.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:
    
    a string representation of the object.
