Access PCD Roles in order to analyze all used entry points

Question

Hi Experts,
I'm facing the situation that we have to report to the customer's management the currently used entry points in our portal implementation. The results of this reports will be used for the further analysis of a future navigation and role concept.
So instead of opening every portal role in the portal content studio I'd prefer an automated approach via portal services. After having read dozens of pcd whitepapers and how to guides, my portal service is able to lookup a specified pcd-folder and search for roles.
The issue that I need to get solved is the following:
It is actually no problem to get via IPcdContext the Attribute, if the role itself is defined as entry point.
What makes it complicated is the fact, that we use a folder underneath the portal role as entry points due to naming and content creation conventions on the customer's site.
DirContext dirCtx;
InitialContext ctx = getInitialContextAspectPersistency();
dirCtx = (DirContext) ctx.lookup("pcd:portal_content/testfolder/");
PcdSearchControls pcdSearchControls = new PcdSearchControls();
pcdSearchControls.setReturningObjFlag(false);
pcdSearchControls.setSearchScope(3);
dirCtx.addToEnvironment(Constants.APPLY_ASPECT_TO_CONTEXTS,Constants.APPLY_ASPECT_TO_CONTEXTS);
NamingEnumeration ne = dirCtx.search("","(com.sap.portal.pcd.gl.ObjectClass=com.sapportals.portal.role)", pcdSearchControls);          
while (ne.hasMoreElements()) {
try{
IPcdSearchResult sR =     (IPcdSearchResult) ne.nextElement();
String location = "pcd:portal_content/testfolder/" + sR.getName();
IPcdContext result = (IPcdContext)ctx.lookup(location);
String entryPoint = result.getAttributes("").get("com.sap.portal.pcd.role.EntryPoint").get().toString();
So what I need is the possibility to iterate through the children of a portal role in order to investigate if it's an entry point or not and in case it is, render the display name of the current child.
Has somebody an idea. Every hint is welcome.
Best regards in advance,
Otto

Hi Otto,
You use the following environment:
env.put(com.sap.portal.directory.Constants.REQUESTED_ASPECT, PcmConstants.ASPECT_SEMANTICS);
This means when you lookup you will get a semantic object and not PCDContext.
So in order to cast to semantic role you will need to do the following casting:
import com.sapportals.portal.pcd.pcm.roles.IPortalRole;
IPortalRole portalCtx = (IPortalRole) ctx.lookup((String) roleList.get(i));
If you need the PCDContext you will need to use the following aspect:
env.put(Constants.REQUESTED_ASPECT, IPcdAttribute.PERSISTENCY_ASPECT);
