Class description
|

|
||
|
|
Naming:
|
||
|
|
|
||
|
|
CLogRecord stands for Logging Record.
|
||
|
|
|
||
|
|
Base class:
|
||
|
|
|
||
|
|
CGenericClass, because it is a class representing a WMI
|
||
|
|
object - its WMI class name is Sce_ConfigurationLogRecord
|
||
|
|
|
||
|
|
Purpose of class:
|
||
|
|
|
||
|
|
(1) Implement Sce_ConfigurationLogRecord WMI class.
|
||
|
|
|
||
|
|
Design:
|
||
|
|
|
||
|
|
(1) Almost trivial other than implementing necessary method as a concrete class.
|
||
|
|
(2) Since log record is to create a log files for human to read, we don't support
|
||
|
|
creating WMI object of this class. We only support PutInstance (writing to the
|
||
|
|
log file).
|
||
|
|
|
||
|
|
Use:
|
||
|
|
|
||
|
|
(1) This class allows us to log information into a log file. That use has been
|
||
|
|
encapulated by CMethodResultRecorder::LogResult. If you have to do it without
|
||
|
|
the help from CMethodResultRecorder, then read that function for details.

Naming:

CErrorInfo error information.
|
||
|
|
|

|
|
Base class:
|
||
|
|
|
||
|
|
none.
|
||
|
|
|
||
|
|
Purpose of class:
|
||
|
|
|
||
|
|
(1) Wrapper for using WMI COM interface of IWbemStatusCodeText.
|
||
|
|
|
||
|
|
Design:
|
||
|
|
|
||
|
|
(1) Instead of requiring each caller to requesting their own IWbemStatusCodeText
|
||
|
|
from WMI, we can create a global (single) instance to translate the HRESULT
|
||
|
|
into text form. This is precisely why we design this class.
|
||
|
|
|
||
|
|
Use:
|
||
|
|
|
||
|
|
(1) This class allows us to log information into a log file. That use has been
|
||
|
|
encapulated by CMethodResultRecorder::LogResult. If you have to do it without
