IOleCacheControl

The IOleCacheControl interface provides proper maintenance of caches. It maintains the caches by connecting the running object's IDataObject implementation to the cache allowing the cache to receive notifications from the running object.

When to Implement

The OLE-provided implementation is used by most handlers and in process servers.

When to Use

Object handlers and in process servers use this interface internally to connect the cache part of the handler to the IDataObject implementation of the running object. Container applications have no need for this interface; they use IRunnableObject or OleRun instead.
