/*************************************************************************
|
|
*
|
|
* How CViewSettingsPersistor is used:
|
|
* There is only one CViewSettingsPersistor object per document.
|
|
*
|
|
* The object stored as static variable inside CNode as CNode needs
|
|
* to access this object frequently.
|
|
*
|
|
* The Document needs to initialize/save the object by loading/savind
|
|
* from/to console file. It calls below ScQueryViewSettingsPersistor.
|
|
*
|
|
* The object is created with first call to ScQueryViewSettingsPersistor.
|
|
* The object is destroyed when DocumentClosed event is received.
|

// This version info is used for MMC1.2 IPersist* interfaces.
|
|
// In MMC2.0, XML maintains versioning using the tags, so this

|
// constant is not used. Look at CViewPersistInfo members Load/Save
|
|
// to see how this version information is used.

// Class: CViewSettingsID
|
|
//
|
|
// Purpose: To identify the result-view-setting-data. The identifier
|
|
// consists of the triplet [ViewID, NodeTypeGUID, Node-Bookmark]
|
|
//
|
|
// We need to persist some result-view-setting-data per node and
|
|
// some per node-type basis.
|
|
//
|
|
// The [ViewID + Node-Bookmark] identifies a node. In this case
|
|
// NodeTypeGUID will be GUID_NULL.
|
|
//
|
|
// The [ViewID + NodeTypeGUID] identifies a nodetype. In this case
|
|
// Node-Bookmark will be invalid object (see CBookmark for invalid obj).
