The <rich:recursiveTreeNodesAdaptor> is an extension of a <rich:treeNodesAdaptor> component that provides the possibility to define data models and process nodes recursively.
Allows to define combined data models
Possibility to define nodes for processing via attributes
Allows to process nodes recursively
The <rich:recursiveTreeNodesAdaptor> component has a "roots" attribute that defines collection to use at the top of recursion.
The "nodes" attribute defines collection to use on another recursion levels.
The "var" attribute is used to access to the current collection element.
The <rich:recursiveTreeNodesAdaptor> component can be nested without any limitations. See the following example.
Example:
...
<rich:tree adviseNodeOpened="#{treeModelBean.adviseNodeOpened}" switchType="client">
<rich:treeNodesAdaptor id="project" nodes="#{loaderBean.projects}" var="project">
<rich:treeNode>
<h:commandLink action="#{project.click}" value="Project: #{project.name}" />
</rich:treeNode>
<rich:recursiveTreeNodesAdaptor id="dir" var="dir" root="#{project.dirs}" nodes="#{dir.directories}">
<rich:treeNode>
<h:commandLink action="#{dir.click}" value="Directory: #{dir.name}" />
</rich:treeNode>
<rich:treeNodesAdaptor id="file" var="file" nodes="#{dir.files}">
<rich:treeNode>
<h:commandLink action="#{file.click}" value="File: #{file.name}" />
</rich:treeNode>
</rich:treeNodesAdaptor>
<rich:treeNodesAdaptor id="file1" var="file" nodes="#{dir.files}">
<rich:treeNode>
<h:commandLink action="#{file.click}" value="File1: #{file.name}" />
</rich:treeNode>
</rich:treeNodesAdaptor>
<rich:recursiveTreeNodesAdaptor id="archiveEntry" var="archiveEntry"
roots="#{dir.files}" nodes="#{archiveEntry.archiveEntries}"
includedRoot="#{archiveEntry.class.simpleName == 'ArchiveFile'}"
includedNode="#{archiveEntry.class.simpleName == 'ArchiveEntry'}">
<rich:treeNode id="archiveEntryNode">
<h:commandLink action="#{archiveEntry.click}" value="Archive entry: #{archiveEntry.name}" />
</rich:treeNode>
</rich:recursiveTreeNodesAdaptor>
