Method Summary

Modifier and Type	Method and Description
static boolean	contains(CellRangeAddress crA, CellRangeAddress crB) Check if the specified range is located inside of this cell range.
static CellRangeAddress	createEnclosingCellRange(CellRangeAddress crA, CellRangeAddress crB) Create an enclosing CellRange for the two cell ranges.
static boolean	hasExactSharedBorder(CellRangeAddress crA, CellRangeAddress crB) Check if the two cell ranges have a shared border.
static int	intersect(CellRangeAddress crA, CellRangeAddress crB) Intersect this range with the specified range.
static CellRangeAddress[]	mergeCellRanges(CellRangeAddress[] cellRanges) Do all possible cell merges between cells of the list so that: if a cell range is completely inside of another cell range, it gets removed from the list if two cells have a shared border, merge them into one bigger cell range

Method Detail

intersect

public static int intersect(CellRangeAddress crA,
                            CellRangeAddress crB)

Intersect this range with the specified range.

Parameters:

crB - - the specified range

Returns:

code which reflects how the specified range is related to this range.
Possible return codes are: NO_INTERSECTION - the specified range is outside of this range;
OVERLAP - both ranges partially overlap;
INSIDE - the specified range is inside of this one
ENCLOSES - the specified range encloses (possibly exactly the same as) this range

mergeCellRanges

public static CellRangeAddress[] mergeCellRanges(CellRangeAddress[] cellRanges)

Do all possible cell merges between cells of the list so that:

if a cell range is completely inside of another cell range, it gets removed from the list if two cells have a shared border, merge them into one bigger cell range

Parameters:

cellRanges -

Returns:

updated List of cell ranges

contains

public static boolean contains(CellRangeAddress crA,
                               CellRangeAddress crB)

Check if the specified range is located inside of this cell range.

Parameters:

crB -

Returns:

true if this cell range contains the argument range inside if it's area

hasExactSharedBorder

public static boolean hasExactSharedBorder(CellRangeAddress crA,
                                           CellRangeAddress crB)

Check if the two cell ranges have a shared border.

Returns:

true if the ranges have a complete shared border (i.e. the two ranges together make a simple rectangular region.

createEnclosingCellRange

public static CellRangeAddress createEnclosingCellRange(CellRangeAddress crA,
                                                        CellRangeAddress crB)

Create an enclosing CellRange for the two cell ranges.

Returns:

enclosing CellRange
