Method Detail

isArraymode

public boolean isArraymode()

setArrayMode

public void setArrayMode(boolean value)

getWorkbook

public EvaluationWorkbook getWorkbook()

getRowIndex

public int getRowIndex()

getColumnIndex

public int getColumnIndex()

getRefEvaluatorForCurrentSheet

public org.apache.poi.ss.formula.SheetRangeEvaluator getRefEvaluatorForCurrentSheet()

getDynamicReference

public ValueEval getDynamicReference(String workbookName,
                                     String sheetName,
                                     String refStrPart1,
                                     String refStrPart2,
                                     boolean isA1Style)

Resolves a cell or area reference dynamically.

Parameters:

workbookName - the name of the workbook containing the reference. If null the current workbook is assumed. Note - to evaluate formulas which use multiple workbooks, a CollaboratingWorkbooksEnvironment must be set up.

sheetName - the name of the sheet containing the reference. May be null (when workbookName is also null) in which case the current workbook and sheet is assumed.

refStrPart1 - the single cell reference or first part of the area reference. Must not be null.

refStrPart2 - the second part of the area reference. For single cell references this parameter must be null

isA1Style - specifies the format for refStrPart1 and refStrPart2. Pass true for 'A1' style and false for 'R1C1' style. TODO - currently POI only supports 'A1' reference style

Returns:

a RefEval or AreaEval
