Interface Summary

Interface	Description
DependencyTracker	Interface for constructing the formula dependency.
EvaluationCell	Abstracts a cell for the purpose of formula evaluation.
EvaluationName	Abstracts a name record for formula evaluation.
EvaluationSheet	Abstracts a sheet for the purpose of formula evaluation.
EvaluationWorkbook	Abstracts a workbook for the purpose of formula evaluation.
ExternSheetReferenceToken	Should be implemented by any org.zkoss.poi.hssf.record.formula.Ptg subclass that needs has an extern sheet index For POI internal use only
FormulaParsingWorkbook	Abstracts a workbook for the purpose of formula parsing.
FormulaRenderingWorkbook	Abstracts a workbook for the purpose of converting formula to text.
IStabilityClassifier	Used to help optimise cell evaluation result caching by allowing applications to specify which parts of a workbook are final.
TwoDEval	Common interface of AreaEval and org.zkoss.poi.hssf.record.formula.eval.AreaEvalBase
WorkbookDependentFormula	Should be implemented by any org.zkoss.poi.hssf.record.formula.Ptg subclass that needs a workbook to render its formula.
WorkbookEvaluator.CacheManager
