Declaration Syntax

Visual Basic

Visual C++

public static ILogicalFilterExpression CreateLogicalFilterExpression(
	LogicalFilterExpressionOperator oper
)

Public Shared Function CreateLogicalFilterExpression ( _
	oper As LogicalFilterExpressionOperator _
) As ILogicalFilterExpression

public:
static ILogicalFilterExpression^ CreateLogicalFilterExpression(
	LogicalFilterExpressionOperator oper
)

Parameters

oper (LogicalFilterExpressionOperator): The operator in the logical filter expression.

Return Value

A new ILogicialFilterExpression.

Remarks

After creating an ILogicalFilterExpression you must add at least two IFieldFilterExpressions to it by calling ILogicalFilterExpression.AddExpression().

Assume you have two IFieldExpressions specifying the field filters "(bid > 5)" and "(ask < 6)" respectively and you created the ILogicalFilterExpression with the AND operator. After you have added the two IFIeldFilterExpressions the resulting ILogicalFilterExpression represents the filter "(bid > 5) AND (ask < 6)"
