FPCWebFilters Collection

The FPCWebFilters collection holds an ordered set of FPCWebFilter objects that represent Web filters.

For a Web filter to work on a Forefront TMG computer, its dynamic-link library (DLL) must be copied to the computer, an object representing it must be created in the FPCWebFilters collection for the computer's array, and it must be registered as an extension of the Forefront TMG Web proxy on the computer by including a reference to it in the computer's InstalledWebFilters property.

When the Add method of this collection is called on an array member to register a Web filter in an array, a reference to the new FPCWebFilter object is automatically created in the FPCRefs collection stored in the InstalledWebFilters property of the local Forefront TMG computer.

When an enterprise with central array management is deployed, objects representing Web filters can also be added to the FPCWebFilters collection in the enterprise configuration. Web filters are not ordered in the FPCWebFilters collection in the enterprise configuration. If the same Web filter is included in the FPCWebFilters collections in the enterprise configuration and an array configuration with different values for FilterDirection property, the enterprise setting overrides the array setting. Conversely, the values of the RelativePath and Priority properties in the enterprise configuration are ignored.

This collection is accessed through the WebFilters property of the FPCExtensions object.

Inheritance

This collection inherits from the FPCPersist object, which contains methods and properties related to the persistent storage of an object's data. They include methods for exporting the object's data to and importing it from an XML document.

Methods

The FPCWebFilters collection defines the following methods.

MethodDescription

Add

Creates a new FPCWebFilter object in the collection and returns a reference to it.

Item

Retrieves the requested FPCWebFilter object from the collection.

MoveDown

Moves the given filter one step down the list of Web filters.

MoveUp

Moves the given filter one step up the list of Web filters.

Remove

Removes the specified FPCWebFilter object from the collection.

Properties

The FPCWebFilters collection defines the following properties.

PropertyDescription

_NewEnum

Gets an enumerator object for the collection.

Count

Gets the number of Web filters in the collection.

Methods Inherited from FPCPersist

NameDescription
CancelWaitForChangesCancels the registration established by the WaitForChanges method (for use in C and C++ programming only).
CanImportReturns a Boolean value that indicates whether the properties of the collection and its elements can be imported from the specified XML document.
ExportWrites the stored values of all the properties of the collection and its elements to the specified XML document.
ExportToFileWrites the stored values of all the properties of the collection and its elements to the specified XML file.
GetServiceRestartMaskRetrieves a 32-bit bitmask of the FpcServices enumerated type that specifies which services need to be restarted for currently unsaved changes to take effect.
ImportCopies the values of all the properties of the collection and its elements from the specified XML document to persistent storage.
ImportFromFileCopies the values of all the properties of the collection and its elements from the specified XML file to persistent storage.
LoadDocPropertiesProvides the XML document's properties so that you can know what information can be imported from the document.
RefreshReads the values of all the properties of the collection and its elements from persistent storage, overwriting any changes that have not been saved.
SaveWrites the current values of all the properties of the collection and its elements to persistent storage.
WaitForChangesRegisters to wait for an event indicating that the contents of the object have changed (for use in C and C++ programming only).

Properties Inherited from FPCPersist

NameDescription
PersistentNameGets the persistent name of the collection. The persistent name of an object is a name that is unique for the object at the respective level of the COM object hierarchy.
VendorParameterSetsGets an FPCVendorParametersSets collection that can hold sets of custom data for extending the collection.

Interfaces for C++ Programming

This collection implements the IFPCWebFilters interface.
