| Interface Summary | |
|---|---|
| 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 | |
|---|---|
| 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 subclasses | 
| AddPtg | Addition operator PTG the "+" binomial operator. | 
| Area2DPtgBase | Common superclass of 2-D area refs | 
| Area3DPtg | Title: Area 3D Ptg - 3D reference (Sheet + Area) | 
| Area3DPxg | Title: 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" This seems to be a Misc Stuff and Junk record. | 
| AttrPtg.SpaceType | |
| BoolPtg | Boolean (boolean) Stores a (java) boolean value in a formula. | 
| ConcatPtg | |
| ControlPtg | Common superclass for tExp tTbl tParen tNlr tAttr tSheet tEndSheet | 
| Deleted3DPxg | An XSSF only representation of a reference to a deleted area | 
| DeletedArea3DPtg | Title: Deleted Area 3D Ptg - 3D referecnce (Sheet + Area) | 
| DeletedRef3DPtg | Title: Deleted Reference 3D Ptg | 
| DividePtg | This PTG implements the standard binomial divide "/" | 
| EqualPtg | |
| ErrPtg | |
| ExpPtg | |
| FuncPtg | |
| FuncVarPtg | |
| GreaterEqualPtg | PTG class to implement greater or equal to | 
| GreaterThanPtg | Greater than operator PTG ">" | 
| IntersectionPtg | |
| IntPtg | Integer (unsigned short integer) Stores an unsigned short value (java int) in a formula | 
| LessEqualPtg | Ptg class to implement less than or equal | 
| LessThanPtg | Less than operator PTG "<". | 
| MemAreaPtg | |
| MemErrPtg | |
| MemFuncPtg | |
| MissingArgPtg | Missing Function Arguments Avik Sengupta <avik at apache.org> | 
| MultiplyPtg | Implements the standard mathmatical multiplication - * | 
| NamePtg | |
| NameXPtg | 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 equal | 
| NumberPtg | Number Stores a floating point value in a formula value stored in a 8 byte field using IEEE notation | 
| OperandPtg | |
| OperationPtg | defines a Ptg that is an operation instead of an operand | 
| 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 as-is on reading back Avik Sengupta <lists@aviksengupta.com> Andrew C. | 
| PercentPtg | Percent PTG. | 
| PowerPtg | |
| Ptg | Ptg represents a syntactic token in a formula. | 
| RangePtg | |
| Ref3DPtg | Title: Reference 3D Ptg | 
| Ref3DPxg | Title: XSSF 3D Reference | 
| RefErrorPtg | RefError - handles deleted cell reference | 
| RefNPtg | RefNPtg | 
| RefPtg | ReferencePtg - handles references (such as A1, A2, IA4) | 
| RefPtgBase | ReferencePtgBase - handles references (such as A1, A2, IA4) | 
| ScalarConstantPtg | Common superclass of all Ptgs that represent simple constant values. | 
| StringPtg | String Stores a String value in a formula value stored in the format <length 2 bytes>char[] | 
| SubtractPtg | |
| TblPtg | This ptg indicates a data table. | 
| UnaryMinusPtg | Unary Plus operator does not have any effect on the operand | 
| UnaryPlusPtg | Unary Plus operator does not have any effect on the operand | 
| UnionPtg | |
| UnknownPtg | |
| ValueOperatorPtg | Common superclass of all value operators. |
