## edu.stanford.smi.protege.util
Class LazyTreeRoot

    java.lang.Object
      edu.stanford.smi.protege.util.LazyTreeNode
          edu.stanford.smi.protege.util.LazyTreeRoot

All Implemented Interfaces:
  TreeNode

Direct Known Subclasses:

    public abstract class LazyTreeRoot

extends LazyTreeNode

The Root node for a lazy tree. Note that this root is never displayed. Its child lazy tree nodes are the apparent roots of the tree.
