Description

Interface Summary

EvaluationCell	Abstracts a cell for the purpose of formula evaluation.
EvaluationName	Abstracts a name record for formula evaluation. For POI internal use only
EvaluationSheet	Abstracts a sheet for the purpose of formula evaluation. For POI internal use only
EvaluationWorkbook	Abstracts a workbook for the purpose of formula evaluation. For POI internal use only
ExternSheetReferenceToken	Should be implemented by any Ptg subclass that needs has an extern sheet index For POI internal use only
FormulaParsingWorkbook	Abstracts a workbook for the purpose of formula parsing. For POI internal use only
FormulaRenderingWorkbook	Abstracts a workbook for the purpose of converting formula to text. For POI internal use only
IStabilityClassifier	Used to help optimise cell evaluation result caching by allowing applications to specify which parts of a workbook are final. The term final is introduced here to denote immutability or 'having constant definition'.
TwoDEval	Common interface of AreaEval and AreaEvalBase
WorkbookDependentFormula	Should be implemented by any Ptg subclass that needs a workbook to render its formula.

Class Summary

CollaboratingWorkbooksEnvironment	Manages a collection of WorkbookEvaluators, in order to support evaluation of formulas across spreadsheets. For POI internal use only
EvaluationWorkbook.ExternalName
EvaluationWorkbook.ExternalSheet
Formula	Encapsulates an encoded formula token array.
FormulaParser	This class parses a formula string into a List of tokens in RPN order.
FormulaRenderer	Common logic for rendering formulas. For POI internal use only
FormulaShifter
FormulaType	Enumeration of various formula types. For POI internal use only
OperationEvaluationContext	Contains all the contextual information required to evaluate an operation within a formula For POI internal use only
SharedFormula	Encapsulates logic to convert shared formulaa into non shared equivalent
SheetNameFormatter	Formats sheet names for use in formula expressions.
WorkbookEvaluator	Evaluates formula cells. For performance reasons, this class keeps a cache of all previously calculated intermediate cell values.

Exception Summary

CollaboratingWorkbooksEnvironment.WorkbookNotFoundException
FormulaParseException	This exception thrown when a supplied formula has incorrect syntax (or syntax currently not supported by POI).
