Method Detail

updateNamedRanges

public abstract void updateNamedRanges(FormulaShifter formulaShifter)

Update named ranges

updateFormulas

public abstract void updateFormulas(FormulaShifter formulaShifter)

Update formulas.

shiftMergedRegions

public abstract java.util.List<CellRangeAddress> shiftMergedRegions(int start,
                                                                    int end,

Shifts, grows, or shrinks the merged regions due to a row shift (RowShifter) or column shift (ColumnShifter). Merged regions that are completely overlaid by shifting will be deleted.

Parameters:

start - the first row or column to be shifted

end - the last row or column to be shifted

n - the number of rows or columns to shift

Returns:

a list of affected merged regions, excluding contain deleted ones

updateConditionalFormatting

public abstract void updateConditionalFormatting(FormulaShifter formulaShifter)

Update conditional formatting

Parameters:

formulaShifter -

updateHyperlinks

public abstract void updateHyperlinks(FormulaShifter formulaShifter)

Shift the Hyperlink anchors (not the hyperlink text, even if the hyperlink is of type LINK_DOCUMENT and refers to a cell that was shifted). Hyperlinks do not track the content they point to.

Parameters:

formulaShifter - the formula shifting policy

shiftRange

public static CellRangeAddress shiftRange(FormulaShifter formulaShifter,
                                          CellRangeAddress cra,
                                          int currentExternSheetIx)
