Method Detail

calculateValue

private void calculateValue(boolean adjust)

Calculates the 1900 based numerical value based upon the utc value held in the date object

Parameters:

adjust - TRUE if we want to incorporate timezone information into the raw UTC date eg. when copying from a spreadsheet

getType

public CellType getType()

Returns the content type of this cell

Returns:

the content type for this cell

getData

public byte[] getData()

Gets the binary data for writing

Overrides:

getData in class CellValue

Returns:

the binary data

getContents

public java.lang.String getContents()

Quick and dirty function to return the contents of this cell as a string. For more complex manipulation of the contents, it is necessary to cast this interface to correct subinterface

Returns:

the contents of this cell as a string

setDate

protected void setDate(java.util.Date d)

Sets the date in this cell

Parameters:

d - the date

setDate

protected void setDate(java.util.Date d,
                       DateRecord.GMTDate a)

Sets the date in this cell, taking the timezone into account

Parameters:

d - the date

a - adjust for timezone

getDate

public java.util.Date getDate()

Gets the date contained in this cell

Returns:

the cell contents

isTime

public boolean isTime()

Indicates whether the date value contained in this cell refers to a date, or merely a time. When writing a cell, all dates are fully defined, even if they refer to a time

Returns:

FALSE if this is full date, TRUE if a time

getDateFormat

public java.text.DateFormat getDateFormat()

Gets the DateFormat used to format the cell. This will normally be the format specified in the excel spreadsheet, but in the event of any difficulty parsing this, it will revert to the default date/time format.

Returns:

the DateFormat object used to format the date in the original excel cell
