How to get the top most layer of an AOT object?

X++Posted by Studio Erudit team 2008-10-19 16:10

The X++ job below shows the top most layer of an AOT object (in this example it is the Address table).

static void se_topLayer(Args _args)

int i;
str strAOTObjectPath = #TablesPath + '\\' + tablestr(Address);
TreeNode treeNode = TreeNode::findNode(strAOTObjectPath);
UtilEntryLevel topLayer;

for (i = 0; i <= 0xf; i++)
if (bitTest(treeNode.applObjectLayerMask(), 1 << i))
topLayer = max(topLayer, i);

print topLayer;

@Swapna, it looks like it just does a bitwise &. This is the function itself:

static boolean bitTest(int _flags, int _test)
return _flags & _test;
