    public class DefaultTristateTreeModel<E>
extends org.zkoss.zul.DefaultTreeModel<E>
implements org.zkoss.zul.ext.TristateModel<E>
    A simple tristate tree data model that uses TreeNode to represent a tree. Thus the whole tree of data must be loaded into memory, and each node must be represented by TreeNode.

    If you want to implement a huge tristate tree that only a visible part shall be loaded, it is better to implement it by extending from AbstractTreeModel, TristateModel.

    This Model is dependent on DefaultTreeModel, for more information please refer it.
