Caplin Systems - CreateFieldFilterExpression Method (field, oper, value)

Creates a new expression that filters the records in the container, based on the value of a field in the record.

The container is filtered by the Caplin Refiner module at Caplin Transformer (see How to use Container Filtering and Sorting).

Declaration Syntax

Visual Basic

Visual C++

IFieldFilterExpression CreateFieldFilterExpression(
	string field,
	FieldFilterExpressionOperator oper,
	string value
)

Function CreateFieldFilterExpression ( _
	field As String, _
	oper As FieldFilterExpressionOperator, _
	value As String _
) As IFieldFilterExpression

IFieldFilterExpression^ CreateFieldFilterExpression(
	String^ field, 
	FieldFilterExpressionOperator oper, 
	String^ value
)

Parameters

field (String): The field in the filter expression.

oper (FieldFilterExpressionOperator): The operator in the filter expression.

value (String): The field value in the filter expression.

Return Value

A new IFieldFilterExpression representing the specified filter.

Examples

Assume only container records where the "bid" field is greater than 5 are required. The filter expression for this is therefore "bid > 5", so the parameters supplied to CreateFieldFilterExpression() are:

CopyC#

field = "bid"
operator = GreaterThan
value = "5"
