/** <P> This class encapsulates the global state of the VM; the |
|
44 |
universe, object heap, interpreter, etc. It is a Singleton and |
|
45 |
must be initialized with a call to initialize() before calling |
|
46 |
getVM(). </P> |
|
47 |
||
48 |
<P> Many auxiliary classes (i.e., most of the VMObjects) keep |
|
49 |
needed field offsets in the form of static Field objects. In a |
|
50 |
debugging system, the VM might be shutdown and re-initialized (on |
|
51 |
a differently-configured build, i.e., 32- vs. 64-bit), and all old |
|
52 |
cached state (including fields and field offsets) must be |
|
53 |
flushed. </P> |
|
54 |
||
55 |
<P> An Observer pattern is used to implement the initialization of |
|
56 |
such classes. Each such class, in its static initializer, |
|
57 |
registers an Observer with the VM class via |
|
58 |
VM.registerVMInitializedObserver(). This Observer is guaranteed to |
|
59 |
be notified whenever the VM is initialized (or re-initialized). To |
|
60 |
implement the first-time initialization, the observer is also |
|
61 |
notified when it registers itself with the VM. (For bootstrapping |
|
62 |
reasons, this implies that the constructor of VM can not |
|
63 |
instantiate any such objects, since VM.soleInstance will not have |
|
64 |
been set yet. This is a bootstrapping issue which may have to be |
|
65 |
revisited later.) </P> |
