TCollectionMethodBrowsable extends TCollectionPropertyBrowsable by showing all methods of the collection itself.

If none are available - e.g. for STL classes like std::list, a TVirtualBranchBrowsable object is created instead. The methods' names will have a "@" prepended, to distinguish them from the contained elements' methods.

This browser helper object is not part of the default list of registered generators (see TVirtualBranchBrowsable::RegisterDefaultGenerators()). If you want to use it, you should call TCollectionMethodBrowsable::Register(); As it extends the functionality of TVirtualBranchBrowsable, one might want to unregister the generator of the "@size()" method by calling TCollectionPropertyBrowsable::Unregister();
