Change the table properties by using x++ code

Here I am changing the Table property is called CacheLookup to "EntireTable"

static void SetTableCacheProperties(Args _args)
{
xInfo xInfo;
treeNode node;
treeNode childNode;
treenodeIterator nodeIterator;
str properties;
str tables;
str TableCache = "EntireTable";

AsciiIo readFile;
str line;
container fileRecord;
str tablePath;
;

readFile = new AsciiIo("F:\\Tables.txt",'R');
fileRecord = readFile.read();

while(fileRecord)
{
xInfo = new xInfo();
node = xInfo.rootNode().AOTfindChild("Data Dictionary");

line = con2str(fileRecord);
node = node.AOTfindChild("Tables");
childNode = node.AOTfindChild(line);
tables = childNode.treeNodeName();

if(tables == line)
{
properties = setProperty(childNode.AOTgetProperties(), 'CacheLookup', TableCache);
info(properties);
childNode.AOTsetProperties(properties);
// instead of above 3 lines can write like this //// childNode.AOTsetProperty('CacheLookup', 'EntireTable');
childNode.AOTsave();
}
fileRecord = readFile.read();

}
childNode.AOTrefresh();
}
