Filter Cache

For dynamic graph building, the filter graph manager maintains a cache of filters. If an application performs a dynamic reconnection, the filter graph manager can cache filters that it removes from the graph. During Intelligent Connect, the filter graph manager tries cached filters first.

In GraphEdit, you can manually add a filter to the cache, as follows:

  1. Add a filter to the graph. (See Add Filters to the Graph.)
  2. Select the filter.
  3. In the Graph menu, click Add Filter To Cache.
  4. GraphEdit removes the filter from the graph and caches it.

To see which filters are in the cache:

  1. In the Graph menu, click Enumerate Cached Filters....
  2. Select the name of the filter.
  3. Click Remove Filter.
