DateTimeSyntax (Java Platform SE 6)

This documentation differs from the official API. Jadeite adds extra features to the API including: variable font sizes, constructions examples, placeholders for classes and methods, and auto-generated “See Also” links. Additionally it is missing some items found in standard Javadoc documentation, including: generics type information, “Deprecated” tags and comments, “See Also” links, along with other minor differences. Please send any questions or feedback to bam@cs.cmu.edu.

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 {@link #getValue() getValue()}. A date-time attribute's Date value is established when it is constructed (see {@link #DateTimeSyntax(Date) 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 Summary
`protected`	`DateTimeSyntax(Date value)` Construct a new date-time attribute with the given `java.util.Date` value.

Method Summary
`boolean`	`equals(Object object)` Returns whether this date-time attribute is equivalent to the passed in object.
`Date`	`getValue()` Returns this date-time attribute's `java.util.Date` value.
`int`	`hashCode()` Returns a hash code value for this date-time attribute.
`String`	`toString()` Returns a string value corresponding to this date-time attribute.

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.

Method Detail

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.

getValue

public Date getValue()

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

Returns:: the Date.

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

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
