Description

Interface Summary
AreaI: Common interface for AreaPtg and Area3DPtg, and their child classes.

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)
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
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
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
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 `Ptg`s 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.
