....that are needed in a particular environment, it reduces the memory footprint and resource usage of mobile nodes. 6 Discussion and related work 6. 1 Related work At the language level, solutions for adaptation problems range from Meta Object Protocols [15, 13] to object based inheritance models [42, 18]. AOP ideas have recently given raise to signi cant e orts in the area of distributed component models. The idea is to express distributed system properties like load balancing and coordination using aspects [35, 2] Auto adaptive systems [3] have recognized the importance of eciently extending ....

....Tool (BIT) LZ97] a collection of Java classes that modify Java byte codes. This system does not address the issue of how to get access to the byte codes; it could be used by any of the LTA approaches discussed here. The ClassFile package [D98] is a similar set of tools. The Darwin project [Kn98] uses this package to add prototype style inheritance to Java. 7. Conclusions We have described the implementation and application of load time adaptation (LTA) a flexible approach to post compilation processing of executable code. LTA intercepts and modifies class binaries as they are 16 ....

....Disjunctive extensions are most useful in modeling components that need to present different interfaces to different clients. A sketch of DARWIN and a detailed description of the way in which it supports independent extensibility of components and dynamic component adaptation is contained in [4]. ....

....all aspects that had to be manually simulated before are now dealt with by the language. This includes the automatic generation of forwarding methods, the correct handling of self and typing. The main aspects of the impossible combination of delegation with subtyping are informally described in [18] (and partly in [15] The language design can be found in [3] Early ideas for a C style implementation are presented in [15] the implementation of an extended Java run time system in [21] A detailed description of object model, typing, language design, implementation and use is forthcoming ....

.... substitutability of delegators for delegatees, it avoids syntactically fragile superclasses and delegatee classes , it avoids accidental overriding of methods with identic signature but unrelated semantics when independently developed classes become part of the same delegation hierarchy ([18], 16] 15] The language extension offers a well defined semantics and minimizes the workload of the programmer while enabling maximal reuse and extensibility. Therefore we propose a design along the lines of LAVA as the method of choice for introducing delegation into Java and any other typed ....

....unanticipated changes to their systems, without discontinuing operation. Not all of them succeeded, e.g. some banks needed more than three days to get their automatic teller machines operational with the new software. Others succeeded thanks to redundant hardware. Detailing the ideas sketched in [Kni98b] this paper explores the feasibility of more timely and inexpensive, purely software based solutions. When active components can neither be directly modified nor unloaded from a running system, we are faced with the problem to change their behavior solely by adding more components. This paper ....
