static

Static function to retrieve enumerator from the ROOT's typesystem.

It has no side effect, except when the load flag is true. In this case, the load of the library containing the scope of the enumerator is attempted. There are two top level code paths: the enumerator is scoped or isn't. If it is not, a lookup in the list of global enums is performed. If it is, two lookups are carried out for its scope: one in the list of classes and one in the list of protoclasses. If a scope with the desired name is found, the enum is searched. If the scope is not found, and the load flag is true, the aforementioned two steps are performed again after an autoload attempt with the name of the scope as key is tried out. If the interpreter lookup flag is false, the ListOfEnums objects are not treated as such, but rather as THashList objects. This prevents any flow of information from the interpreter into the ROOT's typesystem: a snapshot of the typesystem status is taken.
