Verkapselungssystem für ein Rechnersystem

摘要

A computing system having an object management facility (100) is presented. The object management facility (100) manages a plurality of objects (201-205,206-210). Each object (201-205,206-210) references an application (101) designed to run in conjunction with the object management facility (100). The computing system also includes an encapsulation system (844-848) which facilitates the inclusion in the computing system of a first application (846) not designed to run in conjunction with the object management facility (100). The encapsulation facility includes an encapsulation shell (845) and a shell filter (844). The encapsulation shell (845) is referenced by objects (201-205,206-210) as if the encapsulation shell (845) was an application (101) designed to run in conjunction with the object management facility (100). The encapsulation shell (845) also acts as an interface between the object management facility (100) and the first application (846). The shell filter (844) interacts with the encapsulation shell (845) and upon instruction from the encapsulation shell (845) is able to intercept commands from a user (843) to the first application (846). The shell filter (844) also forwards to the first application (846) commands generated by the encapsulation shell.
