Method Detail

buildTree

public TreeRoot buildTree(RaritanPageContext pageContext)

Specified by:

buildTree in interface ITreeBuilder

public TreeRoot refreshTree(TreeRoot theTree,
                            RaritanPageContext pContext)

Description copied from interface: ITreeBuilder

Method to enable dynamic or refreshable trees. Static tree builders should implement this by returning the passed in tree object. Dynamic tree builders should implement this by returning the output of their buildTree( ) method or by pruning/growing the given tree as appropriate.

ITreeBuilders that support "lazy tree node evaluation" should use this method to determine which nodes in the tree need to be updated (TreeNode.needsUpdate( ) method returns true.

Specified by:

refreshTree in interface ITreeBuilder

initialize

public void initialize(org.w3c.dom.Element elem)

Description copied from interface: IConfigurable

This method is called by the Framework as part of the application initializtion. see ConfigurationManager, XMLConfigurationManager, XMLSearchFieldMapFactory, XMLSearchSourceFactory.
