public void setChildMaker(DataNodeFactory childMaker)
DataNode
This method should only be used by applications which wish to restrict the type of node which can appear in a whole subtree of the node hierarchy. The childMaker is normally inherited from parent to child, so for instance customising the childMaker of the tree root by removing certain builders will prevent such nodes from appearing anywhere in the tree.
