Also see Event Consumers, Temporary Event Consumers, and Permanent Event Consumers.

event consumer provider interface

An instance of the __Win32EventConsumerProvider system class that is used to locate an event consumer provider object. A component of the permanent consumer architecture.

Also see Implementing an Event Consumer Provider, permanent consumer, consumer-filter binding, event filter, sink, and logical consumer.

event consumer provider object

A COM object exposing a class identifier (CLSID) and implementing the IWbemEventConsumerProvider interface. It provides access to a sink associated with a logical consumer. A component of the permanent consumer architecture.

Also see Implementing an Event Consumer Provider, permanent consumer, event consumer provider interface, event filter, consumer-filter binding, and sink.

event filter

An instance of the __EventFilter system class that describes an event type and the conditions under which a notification is delivered. A component of the permanent consumer architecture. Also see permanent consumer, event consumer provider interface, event consumer provider object, consumer-filter binding, logical consumer, and sink.

event provider

A COM-based object that generates notifications after receiving an event from an event source. The event source can be a hardware component such as a disk drive or a software component such as a database. Event providers expose a class identifier (CLSID) and support one required interface and one optional interface. All event providers must support the IWbemEventProvider interface. The optional interface is IWbemEventProviderQuerySink. Also see Event Providers.

event query

A query created by WBEM Query Language (WQL), specified by a consumer when it registers to receive event notifications. The query defines the type of event and the conditions under which it is delivered. Also see Event Queries.

extension schema

The third layer of the CIM schema, which includes platform-specific extensions of the CIM schema such as Microsoft® Windows NT®, UNIX, and Microsoft® Exchange Server. Also see common model and core model.
