22 * type that can be used to instantiate and run a JPF object | |
23 * Shell objects can be configured via the JPF 'shell' property, and are | |
24 * typically JPF user interface implementations | |
25 * | |
26 * Instantiation and start() call are done from the JPF.main() method | |
27 * | |
28 * Usually, JPFShell implementors have a <init>(Config) ctor so that they | |
29 * don't need to obtain a new Config object. This is the reason for | |
30 * using a shell *instance* instead of a static main() method - we cannot | |
31 * pass the Config object that was already created by JPF.main() at this point | |
32 * into the shell main(), which means we would either have to turn Config | |
33 * into a singleton (causing problems for multiple JPF runs), or create a new | |
34 * Config object within the shell. Since initialization of Config objects is | |
35 * an expensive task with our new bootstrapping, it seems better to pass the | |
36 * Config object from JPF.main() (which is done automatically when using | |
37 * Config based initialization) | |
