Method Detail

shiftMergedRegions

public List<CellRangeAddress> shiftMergedRegions(int startRow,
                                                 int endRow,
                                                 int n)

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

Specified by:

shiftMergedRegions in class BaseRowColShifter

Parameters:

startRow - the row to start shifting

endRow - the row to end shifting

n - the number of rows to shift

Returns:

an array of affected merged regions, doesn't contain deleted ones

validateShiftParameters

public static void validateShiftParameters(int firstShiftColumnIndex,
                                           int lastShiftColumnIndex,
                                           int step)

Verify that the given column indices and step denote a valid range of columns to shift

Parameters:

firstShiftColumnIndex - the column to start shifting

lastShiftColumnIndex - the column to end shifting

step - length of the shifting step

validateShiftLeftParameters

public static void validateShiftLeftParameters(int firstShiftColumnIndex,
                                               int lastShiftColumnIndex,
                                               int step)

Verify that the given column indices and step denote a valid range of columns to shift to the left

Parameters:

firstShiftColumnIndex - the column to start shifting

lastShiftColumnIndex - the column to end shifting

step - length of the shifting step
