permanent consumer

An event consumer whose registration lasts until it is explicitly cancelled. Permanent consumers specify their queries in instances of the __EventFilter system class. Compare temporary consumer.

Also see Permanent Consumer Architecture, Event Consumers, Temporary Event Consumers, Permanent Event Consumers, event consumer provider interface, event consumer provider object, event filter, consumer-filter binding, sink, and logical consumer.

polymorphism

The calling of a variety of operations using the same interface.

For example, a subclass can redefine the implementation of a method or property inherited from its superclass. The property or method is thereby redefined even if the superclass is used as the interface class.

Thus, the Logical Device class can define the variable status as a string, and can return the values "on" or "off." The Modem subclass of Logical Device can redefine (override) status by returning "on," "off," and "connected." If all Logical Devices are enumerated, any Logical Device that happens to be a modem can return the value "connected" for the status property.

property

A name/value pair that describes the data of the class. Property names cannot begin with a digit and cannot contain white space. Property values must have a valid Managed Object Format (MOF) data type.

property provider

One of the roles of an object provider by which it retrieves and modifies the individual property values of system and/or provider-specific classes. Also see class provider and instance provider.

provider

A COM-based component that enables management applications to access data and event notifications from a variety of sources, such as the system registry or an SNMP device. Also see class provider, instance provider, property provider, and object provider.
