    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.

        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.

      • 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.
