Enumeration of objects is a function of the attribution layer.
Methods that meet this qualification typically return a list of named objects and have a name in the format listXYZ where XYZ is an object type, such as Roles or Actions. The enumeration APIs are those which are prefixed by list and return a java.util.List.
Order is important and relevant within the enumeration methods. CSI calls the providers in the order in which they are configured. Values in lists are concatenated in the order in which providers are called. In some cases, duplicates are removed.
