IWbemHiPerfEnum interface
The IWbemHiPerfEnum interface is used in refresher operations to provide rapid access to enumerations of instance objects. WMI provides an implementation of this interface, which it passes to providers when IWbemHiPerfProvider::CreateRefreshableEnum is called, and it returns to clients when IWbemConfigureRefresher::AddEnum is called.
Client applications can call only the GetObjects method of this interface. Attempts by client applications to call the other IWbemHiPerfEnum methods return WBEM_E_ACCESS_DENIED. Providers call these other methods to update the enumerators whenever a client calls Refresh.
Note This interface is not implemented by the user or by a provider under any circumstances. The implementation provided by WMI is the only one supported.
