Abstract: In an object oriented computer system, a framework mechanism defines behavior that may be accessed by different processing levels in the framework. A shared policy corresponding to the behavior is defined. A policy usage view is defined that includes one or more methods for accessing attributes required by the shared policy. A view adapter is also defined that provides an implementation for invoking the methods on the policy usage view. When a processing level needs the behavior defined by the shared policy, the methods on the view adapter are invoked, which retrieve the required attributes for the shared policy.

Abstract: In an object oriented computer system, a framework mechanism defines an infrastructure for allowing a user to couple processes in the framework together in any suitable way to define a desired process flow. A user first defines a static object structure that corresponds to the specific process flow from one process to the next. The processes in the framework may be flexibly coupled in any suitable order, so a process does not have knowledge of its predecessor or successor processes. Thus, at run-time, a process determines the next step in the process flow from the static object structure. Once a process determines its subsequent process, a client may then create the next process and invoke methods on one or more objects corresponding to the newly-created process. Each process thus determines at run-time the next step in the process flow from the static object structure that the user statically defined to configure the process flow, which defines the desired processing environment.
