Delegation Pattern in Ruby posted on 1249426208|%A: %d %B, %Y|agohover

Sometimes I need to pass an object to an API. But my object does not have the required methods…. And I don't want go and change the 3rd party class definition of my object. In Ruby the solution is easy. Another scenario is I have classes that do parts of the job required. And you need to combine them. There are many ways of implementing the delegation pattern in Ruby:

     end  
   end
