java.lang.Object
  ch.randelshofer.tree.demo.TreevizFileSystemXMLTree

All Implemented Interfaces:

DemoTree

public class TreevizFileSystemXMLTree
extends java.lang.Object
implements DemoTree

TreevizFileSystemXMLTree reads an XML file with the root element named TreevizFileSystem and the top-level child elements Users and Files.

The children of the Users element are interpreted as user account data. Each element should have the following attributes: id(XML-ID), name(Text), created(ISO-Date), isActive(boolean).
Nesting of elements is not allowed. Other than that, there are no more restrictions on the elements.

The children of the Files element are interpreted as a directory tree. Each element should have the following attributes: name(Text), created(ISO-Date), size(Number), and "ownerRef"(id of a user), "creatorRef". Nesting of elements is allowed to form a directory structure. Other than that, there are no more restrictions on the elements. See XMLNodeInfo on how the XML data structure is being interpreted.
