' DESCRIPTION:  A node-based, parent-child, collection class.
'   This class combines treeview-like collections with VB's collection & dictionary objects. Collection items have heirarchy.
'   Can be used without hierarchy by simply not provding a Parent/Sibling Key when adding items


' CHANGE HISTORY
'--------------------------------------------------------------------------------------------------------------
'  Updated the MethodsProps.rtf file, as needed, with every change
' 17 Dec 06. Added support to for saving persistent objects in SaveCollection
'   - persistent objects include stdPictures and stdFonts
' 15 Dec 06. Finalizing project.
'   - Found in specific scenarios, a deserialized object's reference count was one more than it should be. Corrected
'   - When creating arrays, array features are now determined and added to the array attributes for all array types
'   - Variants containing UDTs (user-defined types) are not persisted when saving collection
'       -- UDTs can be saved to a Variant only if the UDT is public in a class within a compiled reference (DLL, OCX, etc)
'   - Variants returning a VarType of vbError or vbDataObject are not persisted when saving collection
'       -- Haven't been able to break those down at this point. IUnknown objects appear, from testing, to be vbDataObjects
' 14 Dec 06.
'   - Completely revamped the serialization and deserialization routines
'     (See GetSerializedItem & SetSerializedItem)
'       -- Now all array types, including variant arrays, are supported
'       -- Arrays are no longer restricted to number of dimensions
'       -- Objects (i.e., Classes) within arrays still need to be serialized by user
'       -- Parameters in Public Event SerializeObject has been changed
'   - Added tons of remarks to the serialization & deserialization routines
' 10 Dec 06.
'   - Playing more with manipulating multidimensional arrays via pointers.
'       -- Removed logic that wrapped the collection item in a variant. This actually
'          forces VB to copy the array and we don't need a copy;
'          we can work directly off the collection item vs a variant wrapper
' 9 Dec 06.
'   - Added SiblingOffsetIndex method
'   - Changed SortCollection to return True if successful
'   - Changed SaveCollection & LoadCollection to return True if successful
'   - Upgraded SaveCollection to auto-save multidimensional arrays of all data types
'       except Variants and Objects/UDTs (those still require SerializeObject event)
'       -- With above exceptions, any multidimensional array containing more than
'          10 dimensions will no longer be able to be saved/persisted
'       -- Resulted in permanent removal of Public Events SerializeStringArray & SerializeArray
'   - Changed ClearKeys method to clear individual branch levels or entire collection
'   - Renamed CountCollection to ItemCount
'   - Renamed CountChildren to ChildCount
'   - Removed IsSiblingOf. Calling myCol.Parent(Index)=myCol.Parent(OtherIndex) results in same thing
'   - Removed CountSiblings. Calling myCol.ChildCount(ParentIndex) results in same thing
'       -- when ParentIndex is zero or vbNullString, root level nodes are counted
' 8 Dec 06.
'   - Found minor bugs in the ShellSortString routine. Fixed
'   - Added optional parameter in MoveItem to allow a new key to be assigned along with the move
'   - Merged the AddKey routine into the FindKey routine; no need to keep it separate
' 7 Dec 06.
'   - the FamilyTreeStructure, when used, was being dimensioned with 3 elements; only 2 are needed. Changed
'   - Added SortCollection method
'       -- Required new supporting routines: ShellSortNumbers, ShellSortString, SortRecursiveNodes, SortNodeLevel
'   - Added additional Relationship enumerations to allow sorting when a child node is added or moved
'       -- Required new supporting routine: GetChildInsertPosition
'   - Added IndexFromKeyIndex method
'   - Changed Parent function to a read/write property
'   - Removed obsolete enumerations
' 6 Dec 06 - Initial release
'--------------------------------------------------------------------------------------------------------------

' Highlights include....
' ============================================================================================================
' 1) Key or key-less items. Keys can be numeric or not, case-sensitive or not. vbNullString is reserved and cannot be used.
' 2) TreeView-Like methods:  AddItem(item,key,parent or sibling), First/Next/PreviousSibling, First/LastChild, etc
' 3) Assigned keys can be changed as desired, but still must be unique if used.
' 4) Nodes, and any children, are moved/deleted in one call
' 5) Provides nice-to-have functions like KeyExists, KeyToIndex, HasChildren, MoveItem (from one node to another) & more
' 6) Change contents of an item without having to delete/re-add
' 7) Fast navigation via doubly linked lists
' 8) Value-based collection; therefore, instantiated objects (i.e., Classes) added to collection are kept alive until removed from collection
' 9) Has ability to save/load collection with restrictions. If you use this ability, declare this class WithEvents
'     See SaveCollection, LoadCollection, and the Public Event
' 10) Now has sorting ability too

' SPECIAL CONSIDERATIONS.....
' ============================================================================================================
' 1) Collection heirarchy are linked lists. Indexes of items should not be cached by you.
'    Indexes change dynamically when items are deleted or a new collection is loaded
' 2) Above being said, keys should be used. If keys aren't used, then you should use the
'    following methods to obtain indexes or to loop thru the collection:
'    - FirstChild, LastChild returns relative indexes based on a passed parent node index/key
'    - FirstSibling, LastSibling returns relative indexes based on passed sibling node index/key
'    - NextSibling, PreviousSibling returns relative indexes based on passed sibling/child node index/key
'    - SiblingOffsetIndex returns sibling x positions from the first or last sibling
'       Whenever a Child or Sibling index method returns zero, you are at the beginning or end of the branch
' 3) Speaking of keys. Since numeric keys can be used too, all methods, that allow
'    a Variant Key/Index, have no way of knowing if "1234" is a numeric key or an index.
'    The type of passed variable determines whether the class treats the parameter as a
'    key or index. VarType of String are ALWAYS treated as Keys, whereas,
'    VarType of Byte,Integer,Long,Single,Double,Currency are ALWAYS treated as Indexes
'    Example:
'       Dim strIndex As String, lngIndex As Long
'       Dim strKey As String, lngKey As Long
'       strIndex="99": lngIndex=99
'       strKey="-123899": lngIndex=-123899
'    Getting Item by Index:  Either Class.Item(lngIndex) or Class.Item(CLng(strIndex))
'    Getting Item by Key: Either Class.Item(strKey) or Class.Item(CStr(lngKey))
' 4) Sorting
'    - The collection can now be sorted. See SortCollection method for restrictions in what can and cannot be sorted.
'    - Another option is to assign keys which are sorted (remember keys can be numeric or not), you can request an
'       item by its key index. Keys are always sorted ascending order. To reverse sort, get the item's key index
'       in descending order.  See IndexFromKeyIndex method.
'    - Yet another option is to dictate where an item is to be added to a collection by properly identifying
'       which Sibling the item should be added before or after.
'   Once items are set in their positions, their positions can only be changed using 4 methods. Even if an item's
'   index changes due to collection item deletes, the remaining items' positions relative to their siblings do not
'   change. The 4 methods that change positions of items are AddItem, MoveItem, MoveChildren, SortCollection

' RESTRICTIONS/LIMITATIONS
' ============================================================================================================
' 1) The LoadCollection, SaveCollection, SaveProperties, GetSerializedItem & the Public Events should be removed for VB5 users.
'    - VB5 does not support creating property bags. i.e., Set ppBag=New PropertyBag is an error in VB5
'    - Should you still want to replicate the LoadCollection/SaveCollection functions, you will have to write your own.
'       Suggest possibly using something similiar to an INI file format and caching the bytes of that file?
'    - Likewise, the example below for SerializeObject, of serailizing a class, will need to be reworked/rethought for VB5 users.
' 2) Sorting on items containing primarily objects can only be successful 100% of the time when all of the objects
'    have a common public property whose value can be compared/sorted. Otherwise, you will need to sort the objects yourself

' PUBLIC EVENTS
' ============================================================================================================
' Should you want this class to cache the collection, it can, except for objects; is that true?....
' NOTE: This class doesn't save anything, it organizes the entire collection into an array
' that is passed via the SaveCollection method. That array can be written by you to a user file or,
' if this is used within a usercontrol, to the property bag (yes, property bags can store byte arrays,
' but not arrays of other data types). That same array must not be altered thereafter and then can be
' passed to the LoadCollection method to re-create the collection. Interested?  Read just a little bit more.

' When your collection contains objects (i.e., Classes), you will need a way of serializing your class
' into a byte array and pass the byte array as a response to the SerializeObject Event when it is
' called.  This event is called from SaveCollection method to get your serialized object and
' also from LoadCollection to pass the serialized array back to you for deserializing

' You will get this event called for each collection item or arrayed item of a collection item that contains an Object
Public Event SerializeObject(ByVal Serialize As Boolean, ByRef collectionObject As Object, ByRef DataArray() As Byte, ByRef ObjectID As String)

'   If Serialize=True :: You are to serialize the passed object into the DataArray()
'       collectionObject. A non-Nothing object within your collection.
'           -- Test the type object, if needed, by using TypeOf(collectionObject) Is classWhatever
'       DataArray(). An empty array you are to fill with the contents of the serailized object
'           -- The serialized object in DataArray can be multidimensional & any LBound.
'       ObjectID (Optional) :: a name you provide that uniquely distinguishes the kind of object it is. This is usually a Class Type.
'           -- When you get the array back for deserialization, you may or many not included flags to indicate which class/object
'               type it was created from (i.e., "cMyClass"). Therefore knowing which class to create from array may be impossible

'   If Serialize=False :: You are to deserialize the DataArray() into the passed collectionObject
'       collectionObject. An empty object to be set from the deserailized array
'           -- i.e, deserialize DataArray into a new classWhatever, then Set collectionObject=classWhatever
'       DataArray(). A populated array you are to use to create a new object
'           -- The DataArray will be same size, dimensions, and have same LBound/UBound you passed when Serialize=True
'       ObjectID (Optional) :: If the ObjectID was provided when Serialize=True, the the value you provided else vbNullString

' How do you serialize an object? For a class object, it is rather simple. This is just one possible way.
' - Create a Friend Function SaveClass(ClassBytes() As Byte) As Boolean
    ' - Within that function Dim myData As New PropertyBag
    ' - Just like an OCX, write your class values into the property bag
    ' - Pass the property bag like so:  ClassBytes() = myData.Contents()
' - Create a Friend Function LoadClass(ClassBytes() As Byte) As Boolean
    ' - Within that function Dim myData As New PropertyBag
    ' - Set the propety bag contents: myData.Contents() = ClassBytes(). Use On Error statement(s)
    ' - Just like an OCX, read your class values from the property bag
