addSubDirectories

public void addSubDirectories(ProjectDBManager projectDBManager)
                       throws java.lang.Throwable

This is to referesh the children of this node form top to bottom. It will remove all the child nodes and recunstruct the tree under this node.

Parameters:

projectDBManager - projectDBManager is the source of getting the directory structure and data

addChildNode

public TreeNode addChildNode(Directory childNode)

Adds a child node to this node

Parameters:

childNode - the node which is to be added as a child node.

getChildNode

public TreeNode getChildNode(java.lang.String directoryID)
