How to iterate project group members: Tables, EDT, etc

Based on S. Kuskov's suggestion and Vania Kashperuk's article, I put down this simple job that iterates Tables and Extended Data Types groups members in a given shared project.

static void tmxIterateProjectGroupMembers(Args _args)
{
    #aot
    #properties
    Str                         projectName = "tmxEDI999";
    ProjectNode                 projectNode;
    ProjectGroupNode            ddProjectGroupNode;
    ProjectGroupNode            edtProjectGroupNode;
    ProjectGroupNode            tblProjectGroupNode;
    ProjectListNode             projectListNode;
    TreeNode                    memberTreeNode;              
    TreeNode                    projectTreeNode;
    TreeNodeIterator            projectIterator;
    
    if(projectName)
    {
        // find all shared projects
        projectListNode = SysTreeNode::getSharedProject();
        // find project with a given name
        projectNode = projectListNode.AOTfindChild(projectName);
        // open it in a separate window in AOT
        projectTreeNode = projectNode.getRunNode();
        // this is the key point after which we can iterate group members
        projectNode = projectNode.loadForInspection();
        // get nested nodes for appropriate names
        ddProjectGroupNode = projectNode.AOTfindChild('DataDictionary');
        edtProjectGroupNode = ddProjectGroupNode.AOTfindChild('Extended Data Types');
        tblProjectGroupNode = ddProjectGroupNode.AOTfindChild('Tables');
        
        // tables
        projectIterator = tblProjectGroupNode.AOTiterator();
        memberTreeNode = projectIterator.next();

        while(memberTreeNode)
        {
            info(strFmt("%1 %2", memberTreeNode.AOTname(), memberTreeNode.treeNodeName()));
            memberTreeNode = projectIterator.next();
        }

        // extended data types
        projectIterator = edtProjectGroupNode.AOTiterator();
        memberTreeNode = projectIterator.next();

        while(memberTreeNode)
        {
            info(strFmt("%1 %2", memberTreeNode.AOTname(), memberTreeNode.treeNodeName()));
            memberTreeNode = projectIterator.next();
        }
    }
}

The key method is loadForInspection. Happy iterating!
