| SpreadsheetDate | | public class SpreadsheetDate extends SerialDate (Code) | | Represents a date using an integer, in a similar fashion to the
implementation in Microsoft Excel. The range of dates supported is
1-Jan-1900 to 31-Dec-9999.
Be aware that there is a deliberate bug in Excel that recognises the year
1900 as a leap year when in fact it is not a leap year. You can find more
information on the Microsoft website in article Q181370:
http://support.microsoft.com/support/kb/articles/Q181/3/70.asp
Excel uses the convention that 1-Jan-1900 = 1. This class uses the
convention 1-Jan-1900 = 2.
The result is that the day number in this class will be different to the
Excel figure for January and February 1900...but then Excel adds in an extra
day (29-Feb-1900 which does not actually exist!) and from that point forward
the day numbers will match.

| Constructor Summary | |
| public | SpreadsheetDate(int day, int month, int year)
Creates a new date instance. | | public | SpreadsheetDate(int serial)
Standard constructor - creates a new date object representing the
specified day number (which should be in the range 2 to 2958465. |
| Method Summary | |
| public int | compare(SerialDate other)
Returns the difference (in days) between this date and the specified
'other' date.
Parameters:
other - the date being compared to. | | public int | compareTo(Object other)
Implements the method required by the Comparable interface.
Parameters:
other - the other object (usually another SerialDate). | | public boolean | equals(Object object)
Tests the equality of this date with an arbitrary object.
This method will return true ONLY if the object is an instance of the
SerialDate base class, and it represents the same day as this
SpreadsheetDate .
Parameters:
object - the object to compare (null permitted). | | public int | getDayOfMonth()
Returns the day of the month. | | public int | getDayOfWeek()
Returns a code representing the day of the week. | | public int | getMonth()
Returns the month (January = 1, February = 2, March = 3). | | public int | getYYYY()
Returns the year (assume a valid range of 1900 to 9999). | | public int | hashCode()
Returns a hash code for this object instance. | | public boolean | isAfter(SerialDate other)
Returns true if this SerialDate represents the same date as the
specified SerialDate.
Parameters:
other - the date being compared to. | | public boolean | isBefore(SerialDate other)
Returns true if this SerialDate represents an earlier date compared to
the specified SerialDate.
Parameters:
other - the date being compared to. | | public boolean | isInRange(SerialDate d1, SerialDate d2)
Returns true if this
SerialDate is within the
specified range (INCLUSIVE). | | public boolean | isInRange(SerialDate d1, SerialDate d2, int include)
Returns true if this SerialDate is within the specified range (caller
specifies whether or not the end-points are included). | | public boolean | isOn(SerialDate other)
Returns true if this SerialDate represents the same date as the
specified SerialDate.
Parameters:
other - the date being compared to. | | public boolean | isOnOrAfter(SerialDate other)
Returns true if this SerialDate represents the same date as the
specified SerialDate.
Parameters:
other - the date being compared to. | | public boolean | isOnOrBefore(SerialDate other)
Returns true if this SerialDate represents the same date as the
specified SerialDate.
Parameters:
other - the date being compared to. | | public Date | toDate()
Returns a java.util.Date equivalent to this date. | | public int | toSerial()
Returns the serial number for the date, where 1 January 1900 = 2
(this corresponds, almost, to the numbering system used in Microsoft
Excel for Windows and Lotus 1-2-3). |
| SpreadsheetDate | | public SpreadsheetDate(int day, int month, int year)(Code) | | Creates a new date instance.
Parameters:
day - the day (in the range 1 to 28/29/30/31).
Parameters:
month - the month (in the range 1 to 12).
Parameters:
year - the year (in the range 1900 to 9999). |
| SpreadsheetDate | | public SpreadsheetDate(int serial)(Code) | | Standard constructor - creates a new date object representing the
specified day number (which should be in the range 2 to 2958465.
Parameters:
serial - the serial number for the day (range: 2 to 2958465). |
| compare | | public int compare(SerialDate other)(Code) | | Returns the difference (in days) between this date and the specified
'other' date.
Parameters:
other - the date being compared to. The difference (in days) between this date and the specified 'other' date. |
| compareTo | | public int compareTo(Object other)(Code) | | Implements the method required by the Comparable interface.
Parameters:
other - the other object (usually another SerialDate). A negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object. |
| equals | | public boolean equals(Object object)(Code) | | Tests the equality of this date with an arbitrary object.
This method will return true ONLY if the object is an instance of the
SerialDate base class, and it represents the same day as this
SpreadsheetDate .
Parameters:
object - the object to compare (null permitted). A boolean. |
| getDayOfMonth | | public int getDayOfMonth()(Code) | | Returns the day of the month.
The day of the month. |
| getDayOfWeek | | public int getDayOfWeek()(Code) | | Returns a code representing the day of the week.

SerialDate class as:
SUNDAY, MONDAY, TUESDAY,
WEDNESDAY, THURSDAY, FRIDAY, and
SATURDAY.
A code representing the day of the week. |
| getMonth | | public int getMonth()(Code) | | Returns the month (January = 1, February = 2, March = 3).

| hashCode | | public int hashCode()(Code) | | Returns a hash code for this object instance.
A hash code. |
| isAfter | | public boolean isAfter(SerialDate other)(Code) | | Returns true if this SerialDate represents the same date as the
