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.
