Reconfiguration

 The reconfiguration loads executable code and links it into the core. The core can switch between various implementations without termination, (s. requirement R5 in chapter , table ). The linking should be done at a high level of transparency to the core (R6-10). From these requirements a design pattern [#!Gr1998!#] can be derived which must be followed by application programmers in order to do dynamic linking of Java classes. The design pattern will be presented in the first part of this section. The second part of the section deals with the framework offered to the application programmer.
