Class description
|
|
|
|
Naming:
|
|
|
|
CSceOperation stands for Sce objects that executes Operation(s).
|
|
|
|
Base class:
|
|
|
|
CGenericClass, because it is a class representing two WMI
|
|
objects - WMI class names are Sce_Operation
|
|
|
|
Purpose of class:
|
|
|
|
(1) Implement Sce_Operation WMI class, which is the only WMI class provided
|
|
by SCE provider that can execute a method. This class has no other property
|
|
other than the capability to execute some methods. See sceprov.mof file for detail.
|
|
|
|
(2) Do all the hard work to start the extension classes' method execution. Currently,
|
|
we have two different extension model (embedding being the one truly used, while Pod
|
|
model is for history reasons).
|
|
|
|
Design:
|
|
|
|
(1) Almost trivial as a sub-class of CGenericClass. Even simpler than most other
|
|
peers because this class doesn't support PutInstnace and GetInstance operations
|
|
since it only implements several static methods.
|
|
|
|
(2) To support our open extension model, this class does trigger all other extension
|
|
classes to execute the method. The private methods are all design for that purpose.
|
|
|
|
(3) ProcessAttachmentData/ExecutePodMethod is to trigger the Pod model extension classes.
|
|
|
|
(4) The rest privates are to trigger the embedding model extension classes.
|
|
|
|
Use:
|
|
|
|
(1) Almost never used directly. Always through the common interface defined by
|
|
CGenericClass.
