This is a Ruby tree! It shows every object from the Ruby Programming Language in a tree format.
# Exception.respond_to? (from ruby core) ### Implementation from Object --- obj.respond_to?(symbol, include_all=false) -> true or false obj.respond_to?(string, include_all=false) -> true or false --- Returns `true` if *obj* responds to the given method. Private and protected methods are included in the search only if the optional second parameter evaluates to `true`. If the method is not implemented, as Process.fork on Windows, File.lchmod on GNU/Linux, etc., false is returned. If the method is not defined, `respond_to_missing?` method is called and the result is returned. When the method name parameter is given as a string, the string is converted to a symbol.
