Returns:
a vector of Nodes.
o getParent 

 public Node getParent(Node childNode)
Returns the parent Node if the given Node.

Parameters:
a - node belonging to the hierarchy
Returns:
a node.

 public Node getParent(Long childNodeID)
Returns the parent Node if the given Node ID.

Parameters:
a - long integer representing the id of a node belonging to the hierarchy
Returns:
a node.
o getPath 

 public Vector getPath(Node mynode)
Returns a list of Nodes representing the path of the Node.

Parameters:
a - node belonging to the hierarchy
Returns:
a vector of Nodes.
o getPath 

 public Vector getPath(Long mynodeID)
Returns a list of Nodes representing the path of the Node ID.

Parameters:
a - long integer representing the id of a node belonging to the hierarchy
Returns:
a vector of Nodes.
o match 

 public Vector match(String matchString)
Looks for entries matching to the string from the hierarchy.
