Framework Base Object
[This topic applies to UMDF 1.x.]
The framework base object is exposed to drivers by the IWDFObject interface. It provides basic functionality that is common across all framework object types. All framework objects are derived from this root object.
When drivers create framework base objects through a call to the IWDFDriver::CreateWdfObject method, they can initially register their IObjectCleanup interfaces so that the framework notifies the driver when the objects are about to be destroyed. Later, drivers can use the IWDFObject::AssignContext method to change how they receive notifications on the framework base object instance.
