Interface Summary Interface Description AreaI Common interface for AreaPtg and Area3DPtg, and their child classes.Pxg An XSSF only special kind of Ptg, which stores the sheet / book reference in string form.Pxg3D An XSSF only special kind of Ptg, which stores a range of sheet / book references in string form. 
Class Summary Class Description AbstractFunctionPtg This class provides the base functionality for Excel sheet functions There are two kinds of function Ptgs  tFunc and tFuncVar Therefore, this class will have ONLY two subclassesAddPtg Addition operator PTG the "+" binomial operator.Area2DPtgBase Common superclass of 2D area refsArea3DPtg Area 3D Ptg  3D reference (Sheet + Area)Area3DPxg XSSF Area 3D Reference (Sheet + Area)AreaErrPtg AreaErr  handles deleted cell area references.AreaI.OffsetArea AreaNPtg Specifies a rectangular area of cells A1:A4 for instance.AreaPtg Specifies a rectangular area of cells A1:A4 for instance.AreaPtgBase Specifies a rectangular area of cells A1:A4 for instance.ArrayPtg ArrayPtg  handles arrays The ArrayPtg is a little weird, the size of the Ptg when parsing initially only includes the Ptg sid and the reserved bytes.AttrPtg "Special Attributes"AttrPtg.SpaceType BoolPtg Boolean (boolean) Stores a (java) boolean value in a formula.ConcatPtg ControlPtg DeferredNamePtg A defined name is only used for parsing and evaluation which will not be written out.Deleted3DPxg An XSSF only representation of a reference to a deleted areaDeletedArea3DPtg Deleted Area 3D Ptg  3D referecnce (Sheet + Area)DeletedRef3DPtg Deleted Reference 3D PtgDividePtg This PTG implements the standard binomial divide "/"EqualPtg ErrPtg ExpPtg FuncPtg FuncVarPtg GreaterEqualPtg PTG class to implement greater or equal toGreaterThanPtg Greater than operator PTG ">"IntersectionPtg IntPtg Integer (unsigned short integer) Stores an unsigned short value (java int) in a formulaLessEqualPtg Ptg class to implement less than or equalLessThanPtg Less than operator PTG "<".MemAreaPtg MemErrPtg MemFuncPtg MissingArgPtg Missing Function ArgumentsMultiplyPtg Implements the standard mathematical multiplication "*"NamePtg See the spec at 2.5.198.76 PtgNameNameXPtg A Name, be that a Named Range or a Function / User Defined Function, addressed in the HSSF External Sheet style.NameXPxg A Name, be that a Named Range or a Function / User Defined Function, addressed in the HSSF External Sheet style.NotEqualPtg Ptg class to implement not equalNumberPtg Number Stores a floating point value in a formula value stored in a 8 byte field using IEEE notationOperandPtg OperationPtg defines a Ptg that is an operation instead of an operandParenthesis2Ptg This Ptg is for multiple area expression generally used in chart series and is only used for parsing and evaluation which will not be written out.ParenthesisPtg While formula tokens are stored in RPN order and thus do not need parenthesis for precedence reasons, Parenthesis tokens ARE written to ensure that user entered parenthesis are displayed asis on reading backPercentPtg Percent PTG.PowerPtg Ptg Ptg
represents a syntactic token in a formula.RangePtg Ref3DPtg Reference 3D PtgRef3DPxg XSSF 3D ReferenceRefErrorPtg RefError  handles deleted cell referenceRefNPtg RefPtg ReferencePtg  handles references (such as A1, A2, IA4)RefPtgBase ReferencePtgBase  handles references (such as A1, A2, IA4)ScalarConstantPtg Common superclass of allPtgs
that represent simple constant values.StringPtg String Stores a String value in a formula value stored in the format <length 2 bytes>char[]SubtractPtg TablePtg TODO: XSSF onlyTblPtg This ptg indicates a data table.UnaryMinusPtg Unary Plus operator  does not have any effect on the operandUnaryPlusPtg Unary Plus operator  does not have any effect on the operandUnionPtg UnknownPtg ValueOperatorPtg Common superclass of all value operators.
