limit number of children

I need to programmatically limit the number of children that a node can have. Some will be allowed 2 or more, some will be allowed only 1. How can I determine the number of children a node currently has, so I can decide whether to allow another.

You could check the size of OutgoingLinks array -

Code
Select All
function onLinkCreating(sender, args)
{
	var link = args.getLink();
	var origin = link.getOrigin();
	args.setCancel(
		origin.getOutgoingLinks().length > 2);
}
