Enumerations

Icon	Type	Description
	FieldFilterExpressionOperator	Enumeration defining the operators that are available for an IFieldFilterExpression.
	IFieldFilterExpression	Represents an expression for filtering the records in a container, based on the value of a record field. The expression takes the form <fieldname> <operator> <value> (for example, bid GreaterThan 5).
	IFilterExpression	Represents an expression of filtering the records in a container based on the value of a record field. The expression takes the form <fieldname> <operator > <value> (for example <bid GreaterThan 5>)
	ILogicalFilterExpression	Represents a compound filter expression for container records consisting of a collection of IFieldFilterExpression. A Compound filter expression takes the form <IFilterExpression><LogicalFilterExpressionOperator><IFilterExpression> [<IFilterExpression><LogicalFilterExpressionOperator><IFilterExpression>...] For example: (bid > 5) AND (ask < 6) or (bid > 5) AND (ask < 6) AND (coupon >= 3) Note: Every occurrence of LogicalFilterExpressionOperator in the filter is of the same type: that is AND or OR only.
	LogicalFilterExpressionOperator	Enumeration defining the logical operations that can be used in an ILogicalFilterExpression.
