Class Method Detail

new(obj)

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

Instance Method Detail

__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()

Duplication support for the object returned by __getobj__.
