DWStrList

DWStrListimplements an indexed singly-linked list for the DWSTRING (Unicode dynamic string) data type.

Usage examples

Using the dotted syntax:

' // Build the linked list
DIM List AS DWStrList
List.Add("Result 1")
List.Add("Result 2")
List.Add("Result 3")
List.Insert(1, "New string")
List.Replace(2, "Replaced string")

' // Retrieve and print the results
FOR i AS LONG = 1 TO List.Count
   PRINT List.Item(i)
NEXT

Using NEW and the pointer syntax:

' // Build the linked list
DIM List AS DWStrList PTR = NEW DWStrList
List->Add("Result 1")
List->Add("Result 2")
List->Add("Result 3")
List->Insert(1, "New string")
List->Replace(2, "Replaced string")

' // Retrieve and print the results
FOR i AS LONG = 1 TO List->Count
   PRINT List->Item(i)
NEXT

' // Delete the list
Delete List

Methods

Name Description
Add Appends an item to the list.
Clear Empties the entire list.
Count Returns the number of items in the list.
Insert Inserts an item at the specific index.
Item Retrieves the item at the specified index.
Remove Removes the specified item from the list.

DVarList

DVarListimplements an indexed singly-linked list for the DVARIANT (dynamic variant) data type. A DVARIANT can contain any kind of data except fixed-length string data (if you pass it as the input it will be converted to a unicode dynamic string).

Usage examples

Using the dotted syntax:

' // Build the linked list
DIM List AS DVarList
List.Add("Result 1")
List.Add("Result 2")
List.Add("Result 3")
List.Insert(1, "New string")
List.Replace(2, "Replaced string")

' // Retrieve and print the results
FOR i AS LONG = 1 TO List.Count
   PRINT List.Item(i)
NEXT

Using NEW and the pointer syntax:

' // Build the linked list
DIM List AS DVarList PTR = NEW DVarList
List->Add("Result 1")
List->Add("Result 2")
List->Add("Result 3")
List->Insert(1, "New string")
List->Replace(2, "Replaced string")

' // Retrieve and print the results
FOR i AS LONG = 1 TO List->Count
   PRINT List->Item(i)
NEXT

' // Delete the list
Delete List
