Break OO privacy: Difference between revisions

Julia's object model is one of structs which contain data and methods which are just functions using those structs, with multiple dispatch, rather than object methods, used to distinguish similarly named calls for different object types. Julia does not therefore enforce any private fields in its structures, since, except for constructors, it does not distinguish object methods from other functions. If private fields or methods are actually needed they can be kept from view by placing them inside a module andwhich is not exportingdirectly accessed by user code. In that case, the user can then break module level themprivacy forby accessexplicitly outsideimporting that module.
