IFilterGraph Interface (Windows Embedded CE 6.0)
1/6/2010
This interface is an abstraction representing a graph of filters. All filters in the graph share the same clock. They might or might not also be connected and stream data between them. This interface allows filters to be joined into a graph and operated as a unit. Unlike the IGraphBuilder interface, this interface does not use heuristics to connect and build the filter graph.
When to Implement
This interface is implemented on the filter graph manager and is not intended for implementation by developers.
When to Use
Applications should not use this interface directly but instead should use the IGraphBuilder interface, which inherits this interface.
Methods in Vtable Order
The following table shows the methods that appear in the Vtable beneath the standard COM methods inherited from IUnknown.
| Method | Description |
|---|---|
Adds a filter to the graph and gives it a name. |
|
Removes a filter from the graph. |
|
Provides an enumerator for all filters in the graph. |
|
Finds a filter that was added with a specified name. |
|
Connects the two IPin objects directly (without intervening filters). |
|
Breaks the existing pin connection and reconnects it to the same pin. |
|
Disconnects this pin, if connected. |
|
Sets the default synchronization source (a clock). |
Requirements
| Windows Embedded CE | Windows CE 2.12 and later |
| Note | Microsoft DirectShow applications and DirectShow filters have different include file and Library requirements For more information, see Setting Up the Build Environment |
