| ITfCleanupContextDurationSink::OnEndCleanupContext ITfCleanupContextDurationSink::OnEndCleanupContext method |
| ITfCleanupContextDurationSink::OnStartCleanupContext ITfCleanupContextDurationSink::OnStartCleanupContext method |
Remarks
A context cleanup occurs when:

- ITfThreadMgr::Deactivate is called while a context is still on the context stack.
