Public Member Functions
FDO_API FdoExpression *	GetLeftExpression ()
	Gets the expression that defines the left side of the comparison.
FDO_API FdoComparisonOperations	GetOperation ()
	Gets the operation to be used to compare the two expressions.
FDO_API FdoExpression *	GetRightExpression ()
	Gets the expression that defines the right side of the comparison.
FDO_API void	Process (FdoIFilterProcessor *p)
	Overrides FdoFilter.Process to pass the FdoComparisonCondition to the appropriate filter processor operation.
FDO_API void	SetLeftExpression (FdoExpression *value)
	Sets the expression that defines the left side of the comparison.
FDO_API void	SetOperation (FdoComparisonOperations operation)
	Sets the operation to be used to compare the two expressions.
