## Public Member Functions
FDO_API FdoExpression * | GetExpression ()
| Gets the expression to be operated on.
FDO_API FdoUnaryOperations | GetOperation ()
| Gets the unary operation to be evaluated by this expression.
FDO_API void | Process (FdoIExpressionProcessor *p)
| Overrides FdoExpression.Process to pass the FdoUnaryExpression to the appropriate expression processor operation.
FDO_API void | SetExpression (FdoExpression *value)
| Sets the expression to be operated on.
FDO_API void | SetOperation (FdoUnaryOperations value)
| Sets the unary operation to be evaluated by this expression.
FDO_API FdoString * | ToString ()
| Returns the well defined text representation of this expression.
FdoString * | ToStringInternal (FdoIdentifierCollection *pIdCol)
| This is an internal method. It returns the well defined text representation of the expression.
## Static Public Member Functions
