Lets assume you are writing a LinkTree component which accepts a
LinkTreeModel parameter. LinkTreeModel has a visitAll method which takes a
LinkNodeVisitor.
You could do something like this (not tested)
LinkTree.tml
-----------
<t:block id="linkBlock">
<t:eventlink event="linkEvent">${linkLabel}</t:eventlink>
</t:block>
LinkTree.java
-------------
public class LinkTree {
@InjectComponent
private RenderCommand linkBlock;
@Property
private String linkEvent;
@Property
private String linkLabel;
@Parameter
private LinkTreeModel model;
public RenderCommand onBeginRender() {
return new RenderCommand() {
public void render(MarkupWriter writer, final
RenderQueue queue) {
model.visitAll(new LinkNodeVisitor() {
public void visit(final LinkTreeNode
node) {
queue.push(new RenderCommand() {
public void
render(MarkupWriter writer, RenderQueue queue2) {
LinkTree.this.linkEvent = node.getEvent();
LinkTree.this.linkLabel = node.getLabel();
queue2.push(linkBlock);
}
});
}
});
}
};
}
}
