For patterns whose quality or classification is considered questionable by us or by the software patterns community as a whole, we also explain briefly what their specific problems are or why they are considered to be of low quality.
||The ABSTRACT FACTORY pattern [GoF95] [POSA4] provides an interface for creating and deleting families of related or dependent objects without coupling clients to concrete classes. A concrete factory implements the factory interface for a given type of object family.
||The ACCEPTOR-CONNECTOR pattern [POSA2] [POSA4] decouples the connection and initialization of cooperating peer services in a networked system from the processing performed by the peer services after they are connected and initialized.
||The ACTIVE OBJECT pattern [POSA2] [POSA4] decouples service requests from service execution to enhance concurrency and simplify synchronized access to objects that reside in their own threads of control. A PROXY represents the interface to the active object, ...|
