The FPCFilterExpressions collection holds a set of FPCFilterExpression objects and defines a filter that you can apply to sessions or log content.
This collection is supplied as an [in] parameter to the ExecuteQuery method of the FPCSessionsMonitor collection and to the ExecuteQuery method of the FPCLogContent collection to specify the filter that will be used in the query.
The FPCFilterExpressions collection is not part of the object hierarchy based on the FPC root object and must be created separately. The following Microsoft Visual Basic Scripting Edition (VBScript) example creates an instance of the FPCFilterExpressions collection:
Set filter = CreateObject("FPC.FPCFilterExpressions")
When creating the filter expressions collection in Visual Basic, use the following:
Dim root As New FPCLib.FPCFilterExpressions
or
Dim root As FPCLib.FPCFilterExpressions
Set root = CreateObject("FPC.FPCFilterExpressions")
When creating the filter expressions collection in C++, you can use the following code to create the collection and a smart pointer to the IFPCFilterExpressions interface:
HRESULT hr;
FPCLib::IFPCFilterExpressionsPtr sipFilterExpressionsCol;
hr = sipFilterExpressionsCol.CreateInstance("FPC.FPCFilterExpressions");
The FPCFilterExpressions collection defines the following methods.
| Method | Description |
|---|---|
| AddDateFilter | Creates a new FPCFilterExpression object representing a date filter expression in the collection and returns a reference to it. |
| AddEnumFilter | Creates a new FPCFilterExpression object representing an enumeration value filter expression in the collection and returns a reference to it. |
| AddIPAddressFilter | Creates a new FPCFilterExpression object representing an IP address filter expression in the collection and returns a reference to it. |
| AddNumericFilter | Creates a new FPCFilterExpression object representing a numeric filter expression in the collection and returns a reference to it. |
| AddStringFilter | Creates a new FPCFilterExpression object representing a string filter expression in the collection and returns a reference to it. |
| Item | Retrieves the requested FPCFilterExpression object from the collection. |
| Remove | Removes the specified FPCFilterExpression object from the collection. |
The FPCFilterExpressions collection has the following properties.
| Property | Description |
|---|---|
| _NewEnum | Gets an enumerator object for the collection. |
| Count | Gets the number of FPCFilterExpression objects in the collection. |
| FilterType | Gets or sets a value from the FpcFilterType enumerated type that specifies whether the collection defines a session filter or a log filter. |
This collection implements the IFPCFilterExpressions interface.
