ItemByClassId(ClassId: MetabaseObjectClass): IMetabaseClassSecurityDescriptor;
ClassId. Object type.
The ItemByClassId property returns parameters of security descriptor by object type.
The property is read-only.
To execute the example make sure that security manager contains the USER user and administrator is allowed to execute all operations with the Express Report object type on setting up parameters of access control on the Discretionary Access Control tab.
Add links to the Metabase, ForeSystem (for Fore.NET example) system assemblies.
