ISearchProtocolThreadContext interface (searchapi.h)

This optional interface enables the protocol handler to perform an action on the thread used for filtering in the protocol host. When the protocol host starts, it first initializes all the protocol handlers, and then it creates the filtering thread(s). The methods on this interface enable protocol handlers to manage their resources that are used by a filtering thread.

Inheritance

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

Methods

The ISearchProtocolThreadContext interface has these methods.

ISearchProtocolThreadContext::ThreadIdle Notifies the protocol handler that the filtering thread is idle, so that the protocol handler can clean up any cache it might have built up.
ISearchProtocolThreadContext::ThreadInit Initializes communication between the protocol handler and the protocol host.
ISearchProtocolThreadContext::ThreadShutdown Notifies the protocol handler that the thread is being shut down.
