If a notice with an identical * id value is already a member of the set, then replace it. If the Benchmarks * resolved property is set, then Loading succeeds, otherwise go to the next * step: Loading.Resolve.Items. * * 3a) Loading.Resolve.Items For each Item in the Benchmark that has an extends * property, resolve it by using the following steps: (1) if the Item is Group, * resolve all the enclosed Items, (2) resolve the extended Item, (3) prepend * the property sequence from the extended Item to the extending Item, (4) if * the Item is a Group, assign values for the id properties of Items copied * from the extended Group, (5) remove duplicate properties and apply property * overrides, and (6) remove the extends property. If any Items extends * property identifier does not match the identifier of a visible Item of the * same type, then Loading fails. If the directed graph formed by the extends * properties includes a loop, then Loading fails. Otherwise, go to the next * step: Loading.Resolve.Profiles. * * SCAP Notes: * * In SCAP use of extended groups and rules is not allowed. * * 3b) Loading.Resolve.Profiles - For each Profile in the Benchmark that has * an extends property, resolve the set of properties in the extending Profile * by applying the following steps: * (1) resolve the extended Profile, * (2) prepend the property sequence from the extended Profile to that of * the extending Profile, * (3) remove all but the last instance of duplicate properties. * * If any Profile's extends property identifier does not match the identifier of * another Profile in the Benchmark, then Loading fails. If the directed graph * formed by the extends properties of Profiles includes a loop, then Loading * fails. Otherwise, go to Loading.Resolve.Abstract. * * 3c) Loading.Resolve.Abstract - For each Item in the Benchmark for which the * abstract property is true, remove the Item. For each Profile in the Benchmark * for which the abstract property is true, remove the Profile. Go to the next * step: Loading.Resolve.Finalize. * * 3d) Loading.Resolve.Finalize - Set the Benchmark resolved property to true; * Loading succeeds. * */ public class XCCDFInterpreter { private static Logger log = Logger.getLogger(XCCDFInterpreter.class.getName());
