AddNumericFilter Method of the IFPCFilterExpressions Interface

Syntax

HRESULT AddNumericFilter(
  [in]  FpcFilterCriteria Criteria,
  [in]  FpcFilterCondition Condition,
  [in]  long Value,
		IFPCFilterExpression** ppNewFilterExpression
);

Parameters

Criteria

Value from the FpcFilterCriteria enumerated type that specifies the parameter (criteria) used in the filter expression.

The following values are valid:

• fpcFilterByBytesReceived
• fpcFilterByBytesSent
• fpcFilterByCacheInfo
• fpcFilterByDestHostPort
• fpcFilterByErrorInfo
• fpcFilterByHTTPCode
• fpcFilterByProcessingTime
• fpcFilterByResultCode
• fpcFilterBySrcPort

Condition

Value from the FpcFilterCondition enumerated type that specifies the required relationship between the parameter (criteria) and the value included in the filter expression.

The following values may be used, but not all of the values are valid for each value of the Criteria parameter:

• fpcEqual
• fpcNotEqual
• fpcGreaterOrEqual
• fpcLessOrEqual

Value

A 32-bit integer value that, together with the Criteria and Condition parameters, forms the filter expression.

ppNewFilterExpression

Address of an interface pointer that on return points to the new IFPCFilterExpression interface created.

Return Value

This method can return one of the following:

• S_OK, indicating that the operation succeeded.
• An error code, indicating that the operation failed. In this case, the [out] parameter returned is a null object.

Syntax

Function AddNumericFilter( _
  ByVal Criteria As FpcFilterCriteria, _
  ByVal Condition As FpcFilterCondition, _
  ByVal Value As Long _
) As FPCFilterExpression

Parameters

Criteria

Value from the FpcFilterCriteria enumerated type that specifies the parameter (criteria) used in the filter expression.

The following values are valid:

• fpcFilterByBytesReceived
• fpcFilterByBytesSent
• fpcFilterByCacheInfo
• fpcFilterByDestHostPort
• fpcFilterByErrorInfo
• fpcFilterByHTTPCode
• fpcFilterByProcessingTime
• fpcFilterByResultCode
• fpcFilterBySrcPort

Condition

Value from the FpcFilterCondition enumerated type that specifies the required relationship between the parameter (criteria) and the value included in the filter expression.

The following values may be used, but not all of the values are valid for each value of the Criteria parameter:

• fpcEqual
• fpcNotEqual
• fpcGreaterOrEqual
• fpcLessOrEqual

Value

A 32-bit integer value that, together with the Criteria and Condition parameters, forms the filter expression.

Return Value

This method returns a reference to the FPCFilterExpression object if successful. Otherwise, an error is raised that can be intercepted by using an error handler.
