TreeSearchElementRenderer

Example

TreeSearchElementRenderer Demo

The TreeSearchElementRenderer is used to provide a User interface that combines TreeBuilder and TreeRenderer to provide browse tree-driven search. In this example, a simple taxonomy is used to provide links to MSN pages. The browse tree is built using a SAXTreeBuilder and rendered with an DropdownMenuTreeRenderer.

JSP Custom tag used to renderer the tree:

  <search:SearchForm
     formName="MSNCategoryTreeForm" 
     action="TreeSearchElementRenderer.jsp" />

XML Configuration for this example:

  <!-- ==================================================================== -->
  <!--  MSN Categories Tree - used in TreeSearchElementRenderer demo.       -->
  <!-- ==================================================================== -->
  <SearchForm name="MSNCategoryTreeForm" 
              rendererClass="com.raritantechnologies.searchApp.taglibrary.SearchFormTableRenderer" >
                 
    <SearchElementRenderer rendererClass="com.raritantechnologies.utils.tree.taglibrary.TreeSearchElementRenderer" 
                           action="TreeSearchElementRenderer.jsp" >

     <TreeBuilder class="com.raritantechnologies.utils.tree.SAXTreeBuilder"
                 fileName="BASE_PATH/data/MSNLinks.xml"
                 treeName="Category" >

         <TreeNode
             nodeTag="Category"
             nameAttribute="name" >
         </TreeNode>

     </TreeBuilder>

     <TreeRenderer class="com.raritantechnologies.utils.tree.taglibrary.DropdownMenuTreeRenderer"
                   hyperlinkTarget="newWindow" />

     <LinkRenderer class="com.raritantechnologies.utils.tree.TaxonomySearchHyperlinkRenderer"
                   hrefParam="href" />

   </SearchElementRenderer>

  </SearchForm>
