How to figure our an ITypeRoot comes from Java Standard Library? [message #872644]

The question is simple (the answer seems not): Given an ITypeRoot, how can I quickly find out if this class belongs to the JRE System Library with JDT means?

http://help.eclipse.org/helios/index.jsp?topic=%2Forg.eclipse.jdt.doc.isv%2Fguide%2Fjdt_int_model.htm shows the model elements that exist in JDT. The JRE System Library as shown on the picture has no associated type.

I went from an IType over its IPackageFragementRoot to an IClasspathEntry but then I got stucked. Is there a simple means to know whether a IPackageFragementRoot comes from the JRE?

Thanks,
Marcel

One probably has to come from another direction. This seems to work.

for (IClasspathEntry entry : project.getRawClasspath()) {
  if (entry.getEntryKind() == IClasspathEntry.CPE_CONTAINER) {
    IPackageFragmentRoot[] subentries = e.project.findPackageFragmentRoots(entry);
    // hope this works always ;)
  }
}

There can be various containers other than the JRE containers. If the entry path contains something like "org.eclipse.jdt.launching.JRE_CONTAINER/...", it should be the JRE container set by JDT. BTW, Android projects could be different.

Thanks for the info.

I'm currently filtering on org.eclipse.jdt.launching.JRE_CONTAINER and mark all PackageFragmentRoots returned by project.findPackageFragmentRoots(entry) as being JavaRuntime libraries.

I should add Android containers and make this configurable.

Thanks,
Marcel
