IEnumFilters interface (strmif.h)

The IEnumFilters interface enumerates the filters in a filter graph. To obtain this interface, call the IFilterGraph::EnumFilters method on the Filter Graph Manager. For more information, see Enumerating Objects in a Filter Graph.

This interface implements a standard Component Object Model (COM) collection object.

If the set of filters in the graph changes, some methods on this interface return VFW_E_ENUM_OUT_OF_SYNC. Call the IEnumFilters::Reset method to resynchronize the enumerator.

The IEnumFilters interface inherits from the IUnknown interface. IEnumFilters also has these types of members:
