RefEval (Keikai Spreadsheet Build 6.1.0.1 API)

All Superinterfaces:

SheetRange, ValueEval

All Known Implementing Classes:

LazyRefEval, RefEvalBase
```
public interface RefEval
extends ValueEval, SheetRange
```
RefEval is the super interface for Ref2D and Ref3DEval. Basically a RefEval impl should contain reference to the original ReferencePtg or Ref3DPtg as well as the final "value" resulting from the evaluation of the cell reference. Thus if the Cell has type CellType.NUMERIC, the contained value object should be of type NumberEval; if cell type is CellType.STRING, contained value object should be of type StringEval

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`int`	`getColumn()`	returns the zero based column index.
`int`	`getFirstSheetIndex()`	returns the first sheet index this applies to
`ValueEval`	`getInnerValueEval(int sheetIndex)`
`int`	`getLastSheetIndex()`	returns the last sheet index this applies to, which will be the same as the first for a 2D and many 3D references
`int`	`getNumberOfSheets()`	returns the number of sheets this applies to
`int`	`getRow()`	returns the zero based row index.
`AreaEval`	`offset(int relFirstRowIx, int relLastRowIx, int relFirstColIx, int relLastColIx)`	Creates an `AreaEval` offset by a relative amount from this RefEval

- Method Detail
  - getInnerValueEval
```
ValueEval getInnerValueEval(int sheetIndex)
```
    Returns:
    
    the evaluated value of the cell referred to by this RefEval on the given sheet
  - getColumn
```
int getColumn()
```
    returns the zero based column index.
  - getRow
```
int getRow()
```
    returns the zero based row index.
  - getFirstSheetIndex
```
int getFirstSheetIndex()
```
    returns the first sheet index this applies to
    
    Specified by:
    
    getFirstSheetIndex in interface SheetRange
  - getLastSheetIndex
```
int getLastSheetIndex()
```
    returns the last sheet index this applies to, which will be the same as the first for a 2D and many 3D references
    
    Specified by:
    
    getLastSheetIndex in interface SheetRange
  - getNumberOfSheets
```
int getNumberOfSheets()
```
    returns the number of sheets this applies to
  - offset
```
AreaEval offset(int relFirstRowIx,
                int relLastRowIx,
                int relFirstColIx,
                int relLastColIx)
```
    Creates an AreaEval offset by a relative amount from this RefEval
