Translating the implicit this into an explicit parameter, the call (in B, with a a delegate) a.foo() translates to A.foo(b), using the type of a for method resolution, but the delegating object b for the this argument. Using inheritance, the analogous code (using capital letters to emphasize that resolution is based on classes, not objects) is:
In the delegate pattern, this is instead accomplished by explicitly passing the original object to the delegate, as an argument to a method. [1] " Delegation" is often used loosely to refer to the distinct concept of forwarding , where the sending object simply uses the corresponding member on the receiving object, evaluated in the context of ...
Business delegate is a Java EE design pattern. [ 1 ] This pattern is directed towards reducing the coupling in between business services and the connected presentation tier, and to hide the implementation details of services (including lookup and accessibility of EJB architecture).
Delegate (CLI), a form of type-safe function pointer used by the Common Language Infrastructure (CLI), specifying both a method to call and optionally an object to call the method on. See also [ edit ]
Adapter Java Design Patterns - Adapter; Delegation, strongly relevant to the object adapter pattern. Dependency inversion principle, which can be thought of as applying the adapter pattern, when the high-level class defines its own (adapter) interface to the low-level module (implemented by an adaptee class). Ports and adapters architecture; Shim
The Factory handles the mapping of decorator and delegate classes and returns the pair associated with a parameter or parameters passed. The interface is the contract between a decorator, a delegate, and the calling class, creating an Inversion of Responsibility. [1] This example use two branches; however, you can have 'N' branches as required.

Clients traverse the object structure and call a dispatching operation accept (visitor) on an element — that "dispatches" (delegates) the request to the "accepted visitor object". The visitor object then performs the operation on the element ("visits the element").
