- Inheritance
The SingleForwardable module provides delegation of specified methods to a designated object, using the methods def_delegator and def_delegators. This module is similar to Forwardable, but it works on objects themselves, instead of their defining classes.
Also see the example at forwardable.rb.
Methods

| Visibility | Signature |

Instance Method Detail
def_delegator(accessor, method, ali = method)
Alias for def_singleton_delegator
def_delegators(accessor, *methods)
Alias for def_singleton_delegators
def_singleton_delegator(accessor, method, ali = method)
Defines a method method which delegates to obj (i.e. it calls the method of the same name in obj). If new_name is provided, it is used as the name for the delegate method.
See the example at forwardable.rb.
def_singleton_delegators(accessor, *methods)
Shortcut for defining multiple delegator methods, but with no provision for using a different name. The following two code samples have the same effect:
single_forwardable.def_delegators :@records, :size, :<<, :map single_forwardable.def_delegator :@records, :size single_forwardable.def_delegator :@records, :<< single_forwardable.def_delegator :@records, :map
See the example at forwardable.rb.
