bundles/org.eclipse.jface.databinding/src/org/eclipse/jface/internal/databinding/provisional/viewers/UnorderedTreeContentProvider.java
/**
     * Sets whether this content provider should add/remove elements using
     * TreePaths (true) or elements (false).
     * 
     * <p></p>
     * <p>When using elements:</p>
     * 
     * <ul>
     * <li>Cycles are permitted (elements can be their own ancestor)</li>
     * <li>Addition, removal, and refresh are slightly faster</li>
     * <li>It is not possible to have more than one content provider per tree</li>
     * <li>The setRootPath(...) method is ignored</li>
     * </ul>
     * 
     * <p></p>
     * <p>When using TreePaths:</p>
     * 
     * <ul>
     * <li>Cycles are not permitted (elements cannot be their own parent)</li>
     * <li>Addition, removal, and refresh are slightly slower</li>
     * <li>It is possible to use more than one content provider in the same tree</li>
     * <li>The setRootPath(...) method can be used to direct the output to a particular
     *     subtree</li>
     * </ul>
