A note about the Tree2 Lazy Loading -- number of children not known blog...by Andrew Robinson

[Todd Patrick <To...@dtn.com>]

Andrew: First of all, thank you - this is greatly appreciated.
 
I only have one question at this point, the line:
 
return <Your business code class here>.loadChildren(this);
 
Means what?
 
Do you have an example of the inner class that could be used?
 
Thanks,
 
--Todd
 
 
 
public class ContentMgmtFolderNode
extends BaseTreeNode
{
ContentMgmtFolderNode(TreeModel model, BaseTreeNode parent, String name)
{
super(model, parent, "folder", name, name, false);
}

/**
* @see com.outlooksoft.cpm.faces.model.BaseTreeNode#loadChildren()
*/
@Override
protected List<BaseTreeNode> loadChildren()
{
return <Your business code class here>.loadChildren(this);
}
}
