Constructor Detail

### AreaReference

    public AreaReference(java.lang.String reference)

  Create an area ref from a string representation. Sheet names containing special characters should be delimited and escaped as per normal syntax rules for formulas.
  The area reference must be contiguous (i.e. represent a single rectangle, not a union of rectangles)

### AreaReference

    public AreaReference(CellReference topLeft,
                         CellReference botRight)

  Creates an area ref from a pair of Cell References.

Method Detail

### isContiguous

    public static boolean isContiguous(java.lang.String reference)

  Is the reference for a contiguous (i.e. unbroken) area, or is it made up of several different parts? (If it is, you will need to call ....

### getWholeRow

    public static AreaReference getWholeRow(java.lang.String start,
                                            java.lang.String end)

### getWholeColumn

    public static AreaReference getWholeColumn(java.lang.String start,
                                               java.lang.String end)

### isWholeColumnReference

    public static boolean isWholeColumnReference(CellReference topLeft,
                                                 CellReference botRight)

  Is the reference for a whole-column reference, such as C:C or D:G ?

### isWholeColumnReference

    public boolean isWholeColumnReference()

### generateContiguous

    public static AreaReference[] generateContiguous(java.lang.String reference)

  Takes a non-contiguous area reference, and returns an array of contiguous area references.

### isSingleCell

    public boolean isSingleCell()

  Returns:
    `false` if this area reference involves more than one cell

### getFirstCell

    public CellReference getFirstCell()

  Returns:
    the first cell reference which defines this area. Usually this cell is in the upper left corner of the area (but this is not a requirement).

### getLastCell

    public CellReference getLastCell()

  Note - if this area reference refers to a single cell, the return value of this method will be identical to that of `getFirstCell()`

  Returns:
    the second cell reference which defines this area. For multi-cell areas, this is cell diagonally opposite the 'first cell'. Usually this cell is in the lower right corner of the area (but this is not a requirement).

### getAllReferencedCells

    public CellReference[] getAllReferencedCells()

  Returns a reference to every cell covered by this area

### formatAsString

    public java.lang.String formatAsString()

  Example return values:

  Result | Comment
  --- | ---
  A1:A1 | Single cell area reference without sheet
  A1:$C$1 | Multi-cell area reference without sheet
  Sheet1!A$1:B4 | Standard sheet name
  'O''Brien''s Sales'!B5:C6' | Sheet name with special characters

  Returns:
    the text representation of this area reference as it would appear in a formula.

### toString

    public java.lang.String toString()

  Overrides:
    `toString` in class `java.lang.Object`
