Abstract: OOP environments comprise composite data structures and internal mechanisms for manipulating those structures. The structures are used to allow a user to realize the power of OOP. Hence, the layout of these structures, the way in which the structures inter-relate, and the manner in which they are built and used are all critical to the utility of a particular OOP environment. It is no surprise, then, that manufacturers and suppliers of OOP environments are constantly striving to design composite data structures and internal mechanisms which maximize user productivity. The internal mechanisms and structures that make up the present invention are collectively referred to as the New Object Model (NOM). The composite data structures and organization of the NOM OOP environment provide significant benefits that are not provided by the environments of the prior art.

Abstract: The present invention utilizes a hardware Window Storage Protection Controller (WSPC) and an Object Encapsulation Enforcement Manager (OEEM) to limit access to object data to only those methods which are encapsulated by the object All of the objects of the computer system which require protection are stored in protected storage by a base storage protection mechanism so that only the mechanisms of the present invention can deny or permit access to the data encapsulated by the objects.

Abstract: A computer system, program product, and method of collecting interned data utilize an interned indicator for an internable data element that indicates whether such a data element is in fact interned within an intern data structure. By maintaining this information, iteration completely through the intern data structure during collection may be avoided, thereby reducing the overhead and improving the efficiency of the collection process. In addition, a computer system, program product, and method of collecting interned data may also determine during a second stage of a collection cycle whether an interned data element, which was determined to be unreachable during a first stage of the collection cycle, has subsequently been accessed through an intern data structure since the beginning of the first stage of the collection cycle.

Abstract: A computer system, program product, and method of managing weak references with a concurrent mark sweep collector inhibit access, while processing weak references, to only those weak references whose referenced objects have not yet been determined to be strongly-reachable (i.e., reachable other than through a weak reference) during a current collection cycle. As such, access to specific weak references during processing thereof by a concurrent mark sweep collector is selectively inhibited to ensure synchronization for all weak references without necessarily stopping the execution of all program threads that attempt to access such weak references while executing in a computer system, thereby minimizing the processing overhead of managing weak references and improving system performance.
