| Class | Description | |
|---|---|---|
 | ArrayExpression | Represents an expression with an array of constant values as the expression. |
| BinaryOperatorExpression | Represents an expression with a binary operator applied to a pair of operands as the expression. |
| BinaryOperatorInfo | Represents the abstract base class for defining binary operators. This class is abstract (MustInherit in Visual Basic) and so cannot be instantiated. |
| BooleanExpression | Represents an expression type with a boolean constant value as the expression. |
| CalcArray | Represents an array of constants during the evaluation of a formula. This class is abstract (MustInherit in Visual Basic) and so cannot be instantiated. |
| CalcConvert | Represents the converting of a value to a specified data type. This is a %[LangWord]static class% and so cannot be inherited or instantiated. |
| CalcError | Represents calculation errors. |
| CalcMissingArgument | Represents a missing argument during the evaluation of a formula. |
| CalcReference | Represents a cell or range reference during the evaluation of a formula. This class is abstract (MustInherit in Visual Basic) and so cannot be instantiated. |
| CellExpression | Represents an expression with a cell reference as the expression. |
| ConstantExpression | Represents the abstract class from which all constant value expression types derive. This class is abstract (MustInherit in Visual Basic) and so cannot be instantiated. |
| DoubleExpression | Represents an expression with a double constant value as the expression. |
| ErrorExpression | Represents an expression with an error constant value as the expression. |
| Expression | Represents the abstract class from which all expression types derive. This class is abstract (MustInherit in Visual Basic) and so cannot be instantiated. |
| ExternalCellExpression | Represents an expression with an external cell reference as the expression. |
| ExternalNameExpression | Represents an expression with an external named variable as the expression. |
| ExternalRangeExpression | Represents an expression with an external range reference as the expression. |
| ExternalReferenceExpression | Represents the abstract class from which all external reference expression types derive. This class is abstract (MustInherit in Visual Basic) and so cannot be instantiated. |
| FunctionExpression | Represents an expression with a function applied to a list of parameters as the expression. |
| FunctionInfo | Represents an abstract base class for defining functions. This class is abstract (MustInherit in Visual Basic) and so cannot be instantiated. |
| IntersectOperatorInfo | Represents the intersect operator. |
| MissingArgumentExpression | Represents an expression with a missing argument constant value as the expression. |
| MultiRangeExpression | Represents an expression with the two values as the reference expression. |
| NameExpression | Represents an expression with a named variable as the expression. |
| OperatorInfo | Represents the abstract base class for defining operators. This class is abstract (MustInherit in Visual Basic) and so cannot be instantiated. |
| ParenthesesExpression | Represents an expression type for parentheses surrounding a specified expression. |
| RangeExpression | Represents an expression with a range reference as the expression. |
| ReferenceExpression | Represents the abstract class from which all reference expression types derive. This class is abstract (MustInherit in Visual Basic) and so cannot be instantiated. |
| TableReferenceExpression | Represents an expression with a table reference as the expression. |
| UnaryOperatorExpression | Represents an expression with a unary operator applied to a single operand as the expression. |
| UnaryOperatorInfo | Represents the abstract base class for defining unary operators. This class is abstract (MustInherit in Visual Basic) and so cannot be instantiated. |
