As far as I understand, Strategy classes are generally stateful but they don't impose any such limitation; an implementor is free to choose to have the Strategy class either stateful or stateless as applicable. The context used in Strategy carries information on which the varying algorithms can act upon. So if the state would be required for the algorithms, then the context could include the state information as part of it.
Just my 2 cents :-) Thanks, Soms. Message: 1 Date: Fri, 21 Apr 2006 03:47:02 -0700 (PDT) From: Nikolay Atanasov <[EMAIL PROTECTED]> Subject: [patterns-discussion] Are strategy classes stateful? To: [email protected] Message-ID: <[EMAIL PROTECTED]> Content-Type: text/plain; charset=iso-8859-1 To All! Hello I have a question about strategy pattern. Can strategy classes be stateful or they are generally stateless?
