Detailed Description

Container class for response functions and their derivatives. ExperimentResponse provides the body class.

The ExperimentResponse class is the "representation" of the response container class. It is the "body" portion of the "handle-body idiom" (see Coplien "Advanced C++", p. 58). The handle class (Response) provides for memory efficiency in management of multiple response objects through reference counting and representation sharing. The body class (ExperimentResponse) actually contains the response data (functionValues, functionGradients, functionHessians, etc.). The representation is hidden in that an instance of ExperimentResponse may only be created by Response. Therefore, programmers create instances of the Response handle class, and only need to be aware of the handle/body mechanisms when it comes to managing shallow copies (shared representation) versus deep copies (separate representation used for history mechanisms).
