Class: SimpleDelegator

A concrete implementation of Delegator, this class provides the means to delegate all supported method calls to the object passed into the constructor and even to change the object being delegated to at a later time with __setobj__ .

Methods

__getobj__ __setobj__ clone dup new

Public Class methods

new(obj)

Pass in the obj you would like to delegate method calls to.

Public Instance methods

__getobj__()

Returns the current object method calls are being delegated to.

__setobj__(obj)

Changes the delegate object to obj.

It’s important to note that this does not cause SimpleDelegator’s methods to change. Because of this, you probably only want to change delegation to objects of the same type as the original delegate.

Here’s an example of changing the delegation object.

  names = SimpleDelegator.new(%w{James Edward Gray II})
  puts names[1]    # => Edward
  names.__setobj__(%w{Gavin Sinclair})
  puts names[1]    # => Sinclair

clone()

Clone support for the object returned by __getobj__.

dup(obj)

Duplication support for the object returned by __getobj__.
