This helper object allows the browsing of methods of objects stored in branches.
They will be depicted by a leaf (or a branch, in case the method returns an object) with a red exclamation mark. Only a subset of all methods will be shown in the browser (see IsMethodBrowsable for the criteria a method has to satisfy).
Obviously, methods are only available if the library is loaded which contains the dictionary for the class to be browsed!
If a branch contains a collection, TMethodBrowsable tries to find out what the contained element is (it will only create methods for the contained elements, but never for the collection). If it fails to extract the type of the contained elements, or if there is no guarantee that the type has any other common denominator than TObject (e.g. in the case of a TObjArray, which can hold any object deriving from TObject) no methods will be added.

Reimplemented from TObject.
Definition at line 111 of file TBranchBrowsable.h.
A TMethod is browsable if it is const, public and not pure virtual, if does not have any parameter without default value, and if it has a (non-void) return value.
A method called *, Get*, or get* will not be browsable if there is a persistent data member called f*, _*, or m*, as data member access is faster than method access. Examples: if one of fX, _X, or mX is a persistent data member, the methods GetX(), getX(), and X() will not be browsable.
