Open method: Tree Structure class

Syntax

Open(StructId, Update)

Description

The Open method opens the tree structure specified by StructId. StructId takes a string value. You cannot read or set any properties of a tree structure until after you open it.

When you open a tree structure, you can specify whether you want to open it for update, or in read-only mode, with the Update parameter. Update takes a Boolean value. Values for Update are:

  • "True": open tree structure in update mode (read/write).

  • "False": open tree structure in read-only mode.

If you try updating or writing to a tree structure opened in read-only mode, your changes are ignored.

Returns

A number: 0 if the method completes successfully.

Example

&MyTreeStruct = &MySession.GetTreeStructure(); 
&REtValue = &MyTreeStruct.Open("ACCESS_GROUP", True);
