X++ list and rename AOT objects (Part I)

This post shows how to list and rename AOT objects. For example, if you need to find all objects whose name and properties start with "ABC", and then replace it with "XYZ".

Part I : List the ABC objects
Actually you might not need to find by this way because you can do it by search feature on AOT. I post this here as it's a good example. The job will pick a node in AOT, then travel through all its sub nodes. The purpose is to find out "ABC" metadata.


To make it easy and can see the result. I change the requirement a bit. All below jobs will be written to find "Phone" in Table Address.


(**Many thanks for the great knowledge from the reference URLs. I put it at the bottom. Until next post!)


Example1 - Simple. Travel only 2 depth steps in table Address.

Code

Result

static void Job10(Args _args) {     TreeNode         treeParentNode = TreeNode::findNode(@'\Data Dictionary\Tables\Address');     TreeNode         treeChildLv01Node,                      treeChildLv02Node;     void printNameAndProperties(str      _prefix,                                 TreeNode _treeNode)     {         TreeNodeName treeNodeName;         str          strProperties;         ;         treeNodeName = _treeNode.treeNodeName();         info(strfmt("%1%2", _prefix, treeNodeName));         strProperties = _treeNode.AOTgetProperties();         if (strScan(strProperties, "#Phone", 1, strLen(strProperties)))             info(strfmt("%1%2", _prefix, strProperties));     }     ;     if (treeParentNode)     {         // Display Name and Properties         printNameAndProperties("", treeParentNode);         // First child         treeChildLv01Node = treeParentNode.AOTfirstChild();         while (treeChildLv01Node)         {             // Display Name and Properties             printNameAndProperties("Lv01--", treeChildLv01Node);             // First child             treeChildLv02Node = treeChildLv01Node.AOTfirstChild();             while (treeChildLv02Node)             {                 // Display Name and Properties                 printNameAndProperties("Lv02----", treeChildLv02Node);                 // Next child                 treeChildLv02Node = treeChildLv02Node.AOTnextSibling();             }             // Next child             treeChildLv01Node = treeChildLv01Node.AOTnextSibling();         }     } //treeParentNode }

Example2 - Recursive. Now, we can travel through all depth steps in table Address.

Code

Result

static void Job10(Args _args) {     TreeNode treeParentNode = TreeNode::findNode(@'\Data Dictionary\Tables\Address');     void printNameAndProperties(str      _prefix,                                 TreeNode _treeNode)     {         str 255      treeNodeName;//TreeNodeName treeNodeName;         str          strProperties;         ;         treeNodeName = _treeNode.treeNodeName();         info(strfmt("%1%2", _prefix, treeNodeName));         strProperties = _treeNode.AOTgetProperties();         if (strScan(strProperties, "#Phone", 1, strLen(strProperties)))             info(strfmt("%1%2", _prefix, strProperties));     }     void writeChildNode(TreeNode _treeNode)     {         TreeNode  childNode;         ;             // Find first child         childNode = _treeNode.AOTfirstChild();         while (childNode)         {             // Display Name and Properties             printNameAndProperties("", childNode);                     // Recursive             writeChildNode(childNode);                     // Find next child             childNode = childNode.AOTnextSibling();         }     }     ;     if (treeParentNode)     {         // Display Name and Properties         printNameAndProperties("", treeParentNode);         // Write children         writeChildNode(treeParentNode);     } //treeParentNode }

Example3 - The last example of this chapter. Recursive with some decoration indent.

Code

Result

static void Job10(Args _args) {     TreeNode treeParentNode = TreeNode::findNode(@'\Data Dictionary\Tables\Address');     int i=0;     void printNameAndProperties(str      _prefix,                                 TreeNode _treeNode)     {         str 255      treeNodeName;//TreeNodeName treeNodeName;         str          strProperties;         ;         treeNodeName = _treeNode.treeNodeName();         info(strfmt("%1%2", _prefix, treeNodeName));         strProperties = _treeNode.AOTgetProperties();         if (strScan(strProperties, "#Phone", 1, strLen(strProperties)))             info(strfmt("%1%2", _prefix, strProperties));     }        void writeChildNode(TreeNode _treeNode)     {         TreeNode  childNode;         Str       strPrefix = "";         int       j;         ;                // Find first child         childNode = _treeNode.AOTfirstChild();         while (childNode)         {             i++;             strPrefix = "";                        // Display Name and Properties             for (j=1; j<=i; j++)                 strPrefix += "====";             printNameAndProperties(strPrefix, childNode);                        // Recursive             writeChildNode(childNode);                        i--;                        // Find next child             childNode = childNode.AOTnextSibling();         }     }     ;     if (treeParentNode)     {         // Display Name and Properties         printNameAndProperties("", treeParentNode);         // Write children         writeChildNode(treeParentNode);     } //treeParentNode }
