TVirtualBranchBrowsable is a base class (not really abstract, but useless by itself) for helper objects that extend TBranch's browsing support. Each registered derived class's generator method is called, which fills all created helper objects into a list which can then be browsed. For details of what these browser helper objects can do, see e.g. TMethodBrowsable, which allows methods to show up in the TBrowser. Only registered helper objects are created. By default, only TMethodBrowsable, TNonSplitBrowsable, and TCollectionPropertyBrowsable are registered (see RegisterDefaultGenerators). You can prevent any of their objects to show up in the browser by unregistering the generator: TMethodBrowsable::Unregister() will stop creating browsable method helper objects from that call on. Note that these helper objects are cached (in TBranch::fBrowsables); already created (and thus cached) browsables will still appear in the browser even after unregistering the corresponding generator. You can implement your own browsable objects and thier generator; see e.g. the simple TCollectionPropertyBrowsable. Note that you will have to register your generator just like any other, and that you should implement the following methods for your own class, mainly for consistency reasons: static void Register() { TVirtualBranchBrowsable::RegisterGenerator(GetBrowsables); } static void Unregister() { TVirtualBranchBrowsable::UnregisterGenerator(GetBrowsables); } where GetBrowsables is a static member function of your class, that creates the browsable helper objects, and has the signature static Int_t GetBrowsables(TList& list, const TBranch* branch, const TVirtualBranchBrowsable* parent=0); It has to return the number of browsable helper objects for parent (or, if NULL, for branch) which are added to the list.

constructor setting all members according to parameters.
Askes all registered generators to fill their browsables into the list. The browsables are generated for a given parent, or (if 0), for a given branch. The branch is passed down to leaves of TVirtualBranchBrowsable, too, as we need to access the branch's TTree to be able to traw.
Check whether the branch (or the parent) contains a collection. If it does, set "contained" to the contained type (if we can retrieve it) and return the TClass for the collection. Set "contained" to the branch's (or parent's) contained object's class for non-collections, returning 0. Only one of "branch" or "parent" can ge given (depending on whether we are creating browsable objects for a branch or for another browsable object)
Returns the full name for TTree::Draw to draw *this. Recursively appends, starting at the top TBranch, all method / object names with proper reference operators (->, .) depending on fTypeIsPointer.
Adds the default generators. The user can remove any of them as follows: TMethodBrowsable::Unregister(); which will cause the browser not to show any methods.
Adds a generator to be called when browsing branches. Called by the Register method, which should be implemented for all derived classes (see e.g. TMethodBrowsable::Register())
Removes a generator from the list of generators to be called when browsing branches. The user can remove any of the generators as follows: TMethodBrowsable::Unregister(); which will cause the browser not to show any methods.
