Field Detail

formats

private java.util.HashMap formats

A hash map of FormatRecords, for random access retrieval when reading in a spreadsheet

formatsList

private java.util.ArrayList formatsList

A list of formats, used when writing out a spreadsheet

xfRecords

private java.util.ArrayList xfRecords

The list of extended format records

nextCustomIndexNumber

private int nextCustomIndexNumber

fonts

private Fonts fonts

A handle to the available fonts

customFormatStartIndex

private static final int customFormatStartIndex

The start index number for custom format records

maxFormatRecordsIndex

private static final int maxFormatRecordsIndex

The maximum number of format records. This is some weird internal Excel constraint

Constructor Detail

FormattingRecords

public FormattingRecords(Fonts f)

Constructor

Parameters:

f - the container for the fonts

Method Detail

addStyle

public final void addStyle(XFRecord xf)
                    throws NumFormatRecordsException

Adds an extended formatting record to the list. If the XF record passed in has not been initialized, its index is determined based on the xfRecords list, and this position is passed to the XF records initialize method

Parameters:

xf - the xf record to add

Throws:

NumFormatRecordsException -

addFormat

public final void addFormat(DisplayFormat fr)
                     throws NumFormatRecordsException

Adds a cell format to the hash map, keyed on its index. If the format record is not initialized, then its index number is determined and its initialize method called. If the font is not a built in format, then it is added to the list of formats for writing out

Parameters:

fr - the format record

isDate

public final boolean isDate(int pos)

Sees if the extended formatting record at the specified position represents a date. First checks against the built in formats, and then checks against the hash map of FormatRecords

Parameters:

pos - the xf format index

Returns:

TRUE if this format index is formatted as a Date

getDateFormat

public final java.text.DateFormat getDateFormat(int pos)

Gets the DateFormat used to format the cell.

Parameters:

pos - the xf format index

Returns:

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

getNumberFormat

public final java.text.NumberFormat getNumberFormat(int pos)

Gets the NumberFormat used to format the cell.

Parameters:

pos - the xf format index

Returns:

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

getFormatRecord

FormatRecord getFormatRecord(int index)

Gets the format record

Parameters:

index -

Returns:

the format record at the specified index

write

public void write(File outputFile)
           throws java.io.IOException

Writes out all the format records and the XF records

Parameters:

outputFile - the file to write to

Throws:

java.io.IOException -

getFonts

protected final Fonts getFonts()

Accessor for the fonts used by this workbook

Returns:

the fonts container

getXFRecord

public final XFRecord getXFRecord(int index)

Gets the XFRecord for the specified index. Used when copying individual cells

Parameters:

index - the XF record to retrieve

Returns:

the XF record at the specified index

getNumberOfFormatRecords

protected final int getNumberOfFormatRecords()

Gets the number of formatting records on the list. This is used by the writable subclass because there is an upper limit on the amount of format records that are allowed to be present in an excel sheet

Returns:

the number of format records present

rationalizeFonts

public IndexMapping rationalizeFonts()

rationalize

public IndexMapping rationalize(IndexMapping fontMapping,
                                IndexMapping formatMapping)

Rationalizes the cell formats. Duplicate formats are removed and the format indexed of the cells adjusted accordingly

rationalizeDisplayFormats

public IndexMapping rationalizeDisplayFormats()

Rationalizes the display formats. Duplicate formats are removed and the format indices of the cells adjusted accordingly. It is invoked immediately prior to writing writing out the sheet

Parameters:

im - the index mapping for the font rationalization
