|
* PURPOSE: Defines the CVirtualSnapinItemImpl class.
|
||
|
|
* This class is used in the same way as the
|
||
|
|
* CBaseSnapinItem class. Except the virtual snapin
|
||
|
|
* class is only supposed to be used in a virtual results pane.
|
||
|
|
* These snapin items are created as needed and go away when
|
||
|
|
* not in use anymore. This is because they are in a virtual
|
||
|
|
* list and so we just do not have memory to support all the
|
||
|
|
* list elements at one time.
|
||
|
|
*
|
||
|
|
* This class puts asserts around all functions that should
|
||
|
|
* NOT be called. Since we are virtual we should never be
|
||
|
|
* a scope item and these asserts protect against this from
|
||
|
|
* happening.
