public class UnaryOperationPtg : OperationPtg, ICloneable

Constructors

UnaryOperationPtg()

Default constructor. To prevent user from creating a token without parameters and to allow descendants do this.

Declaration
public UnaryOperationPtg()

UnaryOperationPtg(DataProvider, Int32, ExcelVersion)

Creates unary operation from the data array and offset of the first byte in it.

Declaration
public UnaryOperationPtg(DataProvider provider, int offset, ExcelVersion version)
Parameters
Type Name Description
DataProvider provider

Object that provides access to the data.
System.Int32 offset

Offset to the token data.
ExcelVersion version

Excel version that was used to infill data provider.

UnaryOperationPtg(String)

Constructs unary operation token by its string representation.

Declaration
public UnaryOperationPtg(string strOperationSymbol)
Parameters
Type Name Description
System.String strOperationSymbol

String representation of the operation that will be created.

Properties

ExcelVersion version
Returns
Type
System.Int32
Overrides

GetTokenId(String)

Gets token code using unary operation string representation.

Declaration
public static FormulaToken GetTokenId(string operationSign)
Parameters
Type Name Description
System.String operationSign

String representation of the unary operation.
Returns
Type Description
FormulaToken

Token code.

PushResultToStack(FormulaUtil, Stack<Object>, Boolean)

Takes all needed operands from the stack and pushes the result of the operation.

Declaration
public override void PushResultToStack(FormulaUtil formulaUtil, Stack<object> operands, bool isForSerialization)
Parameters
Type Name Description
FormulaUtil formulaUtil

Object used for formula parsing.
System.Collections.Generic.Stack<System.Object> operands

Stack that contains all operands and will receive the result of the operation.
System.Boolean isForSerialization
Overrides

ToString(FormulaUtil, Int32, Int32, Boolean, NumberFormatInfo, Boolean)

Converts token to a string.

Declaration
public override string ToString(FormulaUtil formulaUtil, int iRow, int iColumn, bool bR1C1, NumberFormatInfo numberFormat, bool isForSerialization)
Parameters

System.Int32 iColumn

Zero-based row index of the cell that contains this token.
System.Boolean bR1C1

Indicates whether R1C1 notation should be used.
System.Globalization.NumberFormatInfo numberFormat
System.Boolean isForSerialization
Returns
Type Description
System.String

String representation of this token.
