Delegation (object-oriented programming)
In object-oriented programming, delegation refers to evaluating a member ( property or method) of one object (the receiver) in the context of another original object (the sender). Delegation can be done explicitly, by passing the sending object ...

In delegation, an object handles a request by delegating to a second object (the '' ...
, a design pattern implementing this feature.

Forwarding (object-oriented programming) In object-oriented programming, forwarding means that using a member of an object (either a property or a method) results in actually using the corresponding member of a different object: the use is ''forwarded'' to another object. Forwarding is us ...
, an often-confused technique where a sending object uses the corresponding member of another object, without the receiving object having any knowledge of the original, sending object.
